Weak Password Hashing with Static Salt in Siemens SINEC INS

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The affected application uses a password hashing implementation with a static, hardcoded salt shared across all users and installations, and is configured with an insufficient number of iterations. This could allow an attacker to efficiently recover user passwords using brute-force or precomputed attacks, potentially resulting in unauthorized access.

media: renesas: vsp1: Fix NULL pointer deref on module unload

In the Linux kernel, the following vulnerability has been resolved: media: renesas: vsp1: Fix NULL pointer deref on module unload When unloading the module on gen 4, we hit a NULL pointer dereference. This is caused by the cleanup code calling vsp1_drm_cleanup() where it should be calling vsp1_vspx_cleanup(). Fix this by checking the IP version and calling the drm or vspx function accordingly, the same way as the init code does.

chromium-browser: Object lifecycle issue in Dawn

Object lifecycle issue in Dawn in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)

Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws

Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws. To skip a leading 3-byte UTF-8 BOM, decode_json() advances the input scalar's string pointer past the mark with SvPV_set() and restores it only on the normal return path. When decoding aborts through a Perl exception, for example a filter_json_object callback that croaks, the restore is skipped and the scalar is left with its string pointer offset into its own buffer and a shortened length. When that scalar is later freed, the allocator receives an invalid pointer and the interpreter aborts. A single BOM prefixed document decoded with a throwing filter callback crashes any caller.

btrfs: fix double free in create_space_info() error path

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix double free in create_space_info() error path When kobject_init_and_add() fails, the call chain is: create_space_info() -> btrfs_sysfs_add_space_info_type() -> kobject_init_and_add() -> failure -> kobject_put(&space_info->kobj) -> space_info_release() -> kfree(space_info) Then control returns to create_space_info(): btrfs_sysfs_add_space_info_type() returns error -> goto out_free -> kfree(space_info) This causes a double free. Keep the direct kfree(space_info) for the earlier failure path, but after btrfs_sysfs_add_space_info_type() has called kobject_put(), let the kobject release callback handle the cleanup.

ulisesbocchio jasypt-spring-boot Password Hash SimpleGCMConfig.java getSecretKeySaltGenerator hash predictable salt

A weakness has been identified in ulisesbocchio jasypt-spring-boot up to 3.0.5/4.0.4. Affected by this vulnerability is the function getSecretKeySaltGenerator of the file jasypt-spring-boot/src/main/java/com/ulisesbocchio/jasyptspringboot/encryptor/SimpleGCMConfig.java of the component Password Hash Handler. Executing a manipulation can lead to use of a one-way hash with a predictable salt. The attack can be launched remotely. The attack requires a high level of complexity. The exploitation appears to be difficult. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

kernel: NULL pointer dereference in spk_ttyio_ldisc_close function in drivers/accessibility/speakup/spk_ttyio.c

An issue was discovered in drivers/accessibility/speakup/spk_ttyio.c in the Linux kernel through 5.9.9. Local attackers on systems with the speakup driver could cause a local denial of service attack, aka CID-d41227544427. This occurs because of an invalid free when the line discipline is used more than once.

powerpc/xive: fix kmemleak caused by incorrect chip_data lookup

In the Linux kernel, the following vulnerability has been resolved: powerpc/xive: fix kmemleak caused by incorrect chip_data lookup The kmemleak reports the following memory leak: Unreferenced object 0xc0000002a7fbc640 (size 64): comm "kworker/8:1", pid 540, jiffies 4294937872 hex dump (first 32 bytes): 01 00 00 00 00 00 00 00 00 00 09 04 00 04 00 00 ................ 00 00 a7 81 00 00 0a c0 00 00 08 04 00 04 00 00 ................ backtrace (crc 177d48f6): __kmalloc_cache_noprof+0x520/0x730 xive_irq_alloc_data.constprop.0+0x40/0xe0 xive_irq_domain_alloc+0xd0/0x1b0 irq_domain_alloc_irqs_parent+0x44/0x6c pseries_irq_domain_alloc+0x1cc/0x354 irq_domain_alloc_irqs_parent+0x44/0x6c msi_domain_alloc+0xb0/0x220 irq_domain_alloc_irqs_locked+0x138/0x4d0 __irq_domain_alloc_irqs+0x8c/0xfc __msi_domain_alloc_irqs+0x214/0x4d8 msi_domain_alloc_irqs_all_locked+0x70/0xf8 pci_msi_setup_msi_irqs+0x60/0x78 __pci_enable_msix_range+0x54c/0x98c pci_alloc_irq_vectors_affinity+0x16c/0x1d4 nvme_pci_enable+0xac/0x9c0 [nvme] nvme_probe+0x340/0x764 [nvme] This occurs when allocating MSI-X vectors for an NVMe device. During allocation the XIVE code creates a struct xive_irq_data and stores it in irq_data->chip_data. When the MSI-X irqdomain is later freed, xive_irq_free_data() is responsible for retrieving this structure and freeing it. However, after commit cc0cc23babc9 ("powerpc/xive: Untangle xive from child interrupt controller drivers"), xive_irq_free_data() retrieves the chip_data using irq_get_chip_data(), which looks up the data through the child domain. This is incorrect because the XIVE-specific irq data is associated with the XIVE (parent) domain. As a result the lookup fails and the allocated struct xive_irq_data is never freed, leading to the kmemleak report shown above. Fix this by retrieving the irq_data from the correct domain using irq_domain_get_irq_data() and then accessing the chip_data via irq_data_get_irq_chip_data().

A CWE-760: Use of a One-Way Hash with a Predictable Salt vulnerability exists in Modicon M221 (all references, all versions), that could allow an attacker to pre-compute the hash value using dictionary attack technique such as rainbow tables, effectively disabling the protection that an unpredictable salt would provide.

MuPDF 1.23.0 through 1.27.0 Barcode Decoding Double Free

MuPDF versions 1.23.0 through 1.27.0 contain a double-free vulnerability in fz_fill_pixmap_from_display_list() when an exception occurs during display list rendering. The function accepts a caller-owned fz_pixmap pointer but incorrectly drops the pixmap in its error handling path before rethrowing the exception. Callers (including the barcode decoding path in fz_decode_barcode_from_display_list) also drop the same pixmap in cleanup, resulting in a double-free that can corrupt the heap and crash the process. This issue affects applications that enable and use MuPDF barcode decoding and can be triggered by processing crafted input that causes a rendering-time error while decoding barcodes.

net: skb: fix cross-cache free of KFENCE-allocated skb head

In the Linux kernel, the following vulnerability has been resolved: net: skb: fix cross-cache free of KFENCE-allocated skb head SKB_SMALL_HEAD_CACHE_SIZE is intentionally set to a non-power-of-2 value (e.g. 704 on x86_64) to avoid collisions with generic kmalloc bucket sizes. This ensures that skb_kfree_head() can reliably use skb_end_offset to distinguish skb heads allocated from skb_small_head_cache vs. generic kmalloc caches. However, when KFENCE is enabled, kfence_ksize() returns the exact requested allocation size instead of the slab bucket size. If a caller (e.g. bpf_test_init) allocates skb head data via kzalloc() and the requested size happens to equal SKB_SMALL_HEAD_CACHE_SIZE, then slab_build_skb() -> ksize() returns that exact value. After subtracting skb_shared_info overhead, skb_end_offset ends up matching SKB_SMALL_HEAD_HEADROOM, causing skb_kfree_head() to incorrectly free the object to skb_small_head_cache instead of back to the original kmalloc cache, resulting in a slab cross-cache free: kmem_cache_free(skbuff_small_head): Wrong slab cache. Expected skbuff_small_head but got kmalloc-1k Fix this by always calling kfree(head) in skb_kfree_head(). This keeps the free path generic and avoids allocator-specific misclassification for KFENCE objects.

spi: amlogic: spifc-a4: Fix DMA mapping error handling

In the Linux kernel, the following vulnerability has been resolved: spi: amlogic: spifc-a4: Fix DMA mapping error handling Fix three bugs in aml_sfc_dma_buffer_setup() error paths: 1. Unnecessary goto: When the first DMA mapping (sfc->daddr) fails, nothing needs cleanup. Use direct return instead of goto. 2. Double-unmap bug: When info DMA mapping failed, the code would unmap sfc->daddr inline, then fall through to out_map_data which would unmap it again, causing a double-unmap. 3. Wrong unmap size: The out_map_info label used datalen instead of infolen when unmapping sfc->iaddr, which could lead to incorrect DMA sync behavior.

net: spacemit: Fix error handling in emac_tx_mem_map()

In the Linux kernel, the following vulnerability has been resolved: net: spacemit: Fix error handling in emac_tx_mem_map() The DMA mappings were leaked on mapping error. Free them with the existing emac_free_tx_buf() function.

ksmbd: fix use-after-free by using call_rcu() for oplock_info

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free by using call_rcu() for oplock_info ksmbd currently frees oplock_info immediately using kfree(), even though it is accessed under RCU read-side critical sections in places like opinfo_get() and proc_show_files(). Since there is no RCU grace period delay between nullifying the pointer and freeing the memory, a reader can still access oplock_info structure after it has been freed. This can leads to a use-after-free especially in opinfo_get() where atomic_inc_not_zero() is called on already freed memory. Fix this by switching to deferred freeing using call_rcu().

rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net()

In the Linux kernel, the following vulnerability has been resolved: rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net() When idtab allocation fails, net is not registered with rio_add_net() yet, so kfree(net) is sufficient to release the memory. Set mport->net to NULL to avoid dangling pointer.

wifi: brcmfmac: Fix potential kernel oops when probe fails

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: Fix potential kernel oops when probe fails When probe of the sdio brcmfmac device fails for some reasons (i.e. missing firmware), the sdiodev->bus is set to error instead of NULL, thus the cleanup later in brcmf_sdio_remove() tries to free resources via invalid bus pointer. This happens because sdiodev->bus is set 2 times: first in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix this by chaning the brcmf_sdio_probe() function to return the error code and set sdio->bus only there.

hfsplus: ensure sb->s_fs_info is always cleaned up

In the Linux kernel, the following vulnerability has been resolved: hfsplus: ensure sb->s_fs_info is always cleaned up When hfsplus was converted to the new mount api a bug was introduced by changing the allocation pattern of sb->s_fs_info. If setup_bdev_super() fails after a new superblock has been allocated by sget_fc(), but before hfsplus_fill_super() takes ownership of the filesystem-specific s_fs_info data it was leaked. Fix this by freeing sb->s_fs_info in hfsplus_kill_super().

xdp: fix invalid wait context of page_pool_destroy()

In the Linux kernel, the following vulnerability has been resolved: xdp: fix invalid wait context of page_pool_destroy() If the driver uses a page pool, it creates a page pool with page_pool_create(). The reference count of page pool is 1 as default. A page pool will be destroyed only when a reference count reaches 0. page_pool_destroy() is used to destroy page pool, it decreases a reference count. When a page pool is destroyed, ->disconnect() is called, which is mem_allocator_disconnect(). This function internally acquires mutex_lock(). If the driver uses XDP, it registers a memory model with xdp_rxq_info_reg_mem_model(). The xdp_rxq_info_reg_mem_model() internally increases a page pool reference count if a memory model is a page pool. Now the reference count is 2. To destroy a page pool, the driver should call both page_pool_destroy() and xdp_unreg_mem_model(). The xdp_unreg_mem_model() internally calls page_pool_destroy(). Only page_pool_destroy() decreases a reference count. If a driver calls page_pool_destroy() then xdp_unreg_mem_model(), we will face an invalid wait context warning. Because xdp_unreg_mem_model() calls page_pool_destroy() with rcu_read_lock(). The page_pool_destroy() internally acquires mutex_lock().

Using xa without rcu_read_lock() here is safe. xa is freed by __xdp_mem_allocator_rcu_free() and this is called by call_rcu() of mem_xa_remove(). The mem_xa_remove() is called by page_pool_destroy() if a reference count reaches 0. The xa is already protected by the reference count mechanism well in the control plane. So removing rcu_read_lock() for page_pool_destroy() is safe.
