wifi: iwlwifi: mvm: don't leak a link on AP removal

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't leak a link on AP removal Release the link mapping resource in AP removal. This impacted devices that do not support the MLD API (9260 and down). On those devices, we couldn't start the AP again after the AP has been already started and stopped.

usb: dwc3: fix fault at system suspend if device was already runtime suspended

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: fix fault at system suspend if device was already runtime suspended If the device was already runtime suspended then during system suspend we cannot access the device registers else it will crash. Also we cannot access any registers after dwc3_core_exit() on some platforms so move the dwc3_enable_susphy() call to the top.

idpf: fix idpf_vc_core_init error path

In the Linux kernel, the following vulnerability has been resolved: idpf: fix idpf_vc_core_init error path In an event where the platform running the device control plane is rebooted, reset is detected on the driver. It releases all the resources and waits for the reset to complete. Once the reset is done, it tries to build the resources back. At this time if the device control plane is not yet started, then the driver timeouts on the virtchnl message and retries to establish the mailbox again. In the retry flow, mailbox is deinitialized but the mailbox workqueue is still alive and polling for the mailbox message. This results in accessing the released control queue leading to null-ptr-deref. Fix it by unrolling the work queue cancellation and mailbox deinitialization in the reverse order which they got initialized.

kernel: lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow

An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow.

kernel: ovl: fix use after free in struct ovl_aio_req

A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected.

cipso: Fix data-races around sysctl.

In the Linux kernel, the following vulnerability has been resolved: cipso: Fix data-races around sysctl. While reading cipso sysctl variables, they can be changed concurrently. So, we need to add READ_ONCE() to avoid data-races.

ipv4: Fix a data-race around sysctl_fib_sync_mem.

In the Linux kernel, the following vulnerability has been resolved: ipv4: Fix a data-race around sysctl_fib_sync_mem. While reading sysctl_fib_sync_mem, it can be changed concurrently. So, we need to add READ_ONCE() to avoid a data-race.

sysctl: Fix data-races in proc_dou8vec_minmax().

In the Linux kernel, the following vulnerability has been resolved: sysctl: Fix data-races in proc_dou8vec_minmax(). A sysctl variable is accessed concurrently, and there is always a chance of data-race. So, all readers and writers need some basic protection to avoid load/store-tearing. This patch changes proc_dou8vec_minmax() to use READ_ONCE() and WRITE_ONCE() internally to fix data-races on the sysctl side. For now, proc_dou8vec_minmax() itself is tolerant to a data-race, but we still need to add annotations on the other subsystem's side.

icmp: Fix a data-race around sysctl_icmp_errors_use_inbound_ifaddr.

In the Linux kernel, the following vulnerability has been resolved: icmp: Fix a data-race around sysctl_icmp_errors_use_inbound_ifaddr. While reading sysctl_icmp_errors_use_inbound_ifaddr, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader.

Mozilla: Arbitrary file read from a compromised content process

An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary files via clipboard-related IPC messages.<br>*This bug only affects Thunderbird for Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird < 102.6.

Linux Kernel Driver memory.c use after free

A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is an unknown function of the file mm/memory.c of the component Driver Handler. The manipulation leads to use after free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211020.

NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer handler, where an unhandled return value can lead to a null-pointer dereference, which may lead to denial of service.

kernel: use-after-free due to improper update of reference count in net/sched/cls_u32.c

Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions.

kernel: Use after free via PI futex state

An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.

drm/amdkfd: amdkfd_free_gtt_mem clear the correct pointer

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: amdkfd_free_gtt_mem clear the correct pointer Pass pointer reference to amdgpu_bo_unref to clear the correct pointer, otherwise amdgpu_bo_unref clear the local variable, the original pointer not set to NULL, this could cause use-after-free bug.
