Ubuntu Security Notice USN-5729-1

Ubuntu Security Notice 5729-1 - It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service. Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel contained an out-of-bounds read vulnerability in the x86 JIT compiler. A local attacker could possibly use this to cause a denial of service or expose sensitive information.

Ubuntu Security Notice USN-5693-1

Ubuntu Security Notice 5693-1 - David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service.

CVE-2022-41686: en/security-disclosure/2022/2022-10.md · OpenHarmony/security - Gitee.com

OpenHarmony-v3.1.2 and prior versions, 3.0.6 and prior versions have an Out-of-bound memory read and write vulnerability in /dev/mmz_userdev device driver. The impact depends on the privileges of the attacker. The unprivileged process run on the device could read out-of-bound memory leading sensitive to information disclosure. The processes with system user UID run on the device would be able to write out-of-bound memory which could lead to unspecified memory corruption.

Ubuntu Security Notice USN-5650-1

Ubuntu Security Notice 5650-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

CVE-2022-40768: git/torvalds/linux.git - Linux kernel source tree

drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.

CVE-2022-2905: Invalid Bug ID

An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data.

CVE-2022-39190: netfilter: nf_tables: disallow binding to already bound chain · torvalds/linux@e02f0d3

An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain.

CVE-2022-3028: af_key: Do not call xfrm_probe_algs in parallel · torvalds/linux@ba953a9

A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.

CVE-2022-2978: fix UAF/GPF bug in nilfs_mdt_destroy

A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
