kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.

kernel: buffer overflow in nft_set_desc_concat_parse()

A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code.

kernel: use-after-free in ath9k_htc_probe_device() could cause an escalation of privileges

A use-after-free flaw was found in the Linux kernel’s Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system.

kernel: possible race condition in drivers/tty/tty_buffers.c

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.

kernel: use-after-free and memory errors in ext4 when mounting and operating on a corrupted image

A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service.

kernel: malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory

When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds.

Kernel: security regression for cve-2018-13405

A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS.

kernel: unaccounted ipc objects in Linux kernel lead to breaking memcg limits and DoS attacks

A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability.

sqlite: error mishandling because of incomplete fix of CVE-2019-19880

multiSelect in select.c in SQLite 3.30.1 mishandles certain errors during parsing, as demonstrated by errors from sqlite3WindowRewrite() calls. NOTE: this vulnerability exists because of an incomplete fix for CVE-2019-19880.

sqlite: zipfileUpdate in ext/misc/zipfile.c mishandles a NULL pathname during an update of a ZIP archive

zipfileUpdate in ext/misc/zipfile.c in SQLite 3.30.1 mishandles a NULL pathname during an update of a ZIP archive.

sqlite: mishandling of certain uses of SELECT DISTINCT involving a LEFT JOIN in flattenSubquery in select.c leads to a NULL pointer dereference

flattenSubquery in select.c in SQLite 3.30.1 mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. This can cause a NULL pointer dereference (or incorrect results).

sqlite: invalid pointer dereference in exprListAppendList in window.c

exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference because constant integer values in ORDER BY clauses of window definitions are mishandled.

libxml2: Use after free triggered by XPointer paths beginning with range-to

Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function.

The mod_copy module in ProFTPD 1.3.5 allows remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands.

kernel: A possible deadlock in dm_get_inactive_table in dm- ioctl.c leads to dos

A denial of service problem was found, due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-component.

open-vm-tools: SAML token signature bypass

A malicious actor that has been granted Guest Operation Privileges https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-security/GUID-6A952214-0E5E-4CCF-9D2A-90948FF643EC.html  in a target virtual machine may be able to elevate their privileges if that target virtual machine has been assigned a more privileged Guest Alias https://vdc-download.vmware.com/vmwb-repository/dcr-public/d1902b0e-d479-46bf-8ac9-cee0e31e8ec0/07ce8dbd-db48-4261-9b8f-c6d3ad8ba472/vim.vm.guest.AliasManager.html .

kernel: out-of-bounds write in hw_atl_utils_fw_rpc_wait() in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c

In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value.

kernel: use-after-free in hso_free_net_device() in drivers/net/usb/hso.c

hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.

kernel: when setting font with malicious data by ioctl PIO_FONT, kernel will write memory out of bounds
