CVE-2022-49271 – cifs: prevent bad output lengths in smb2_ioctl_query_info()

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: cifs: prevent bad output lengths in smb2_ioctl_query_info() When calling smb2_ioctl_query_info() with smb_query_info::flags=PASSTHRU_FSCTL and smb_query_info::output_buffer_length=0, the following would return 0x10 buffer = memdup_user(arg + sizeof(struct smb_query_info), qi.output_buffer_length); if (IS_ERR(buffer)) { kfree(vars); return PTR_ERR(buffer); } rather than a valid pointer thus making IS_ERR() check fail. This would then cause a... • https://git.kernel.org/stable/c/9963ccea6087268e1275b992dca5d0dd4b938765 •

CVE-2022-49267 – mmc: core: use sysfs_emit() instead of sprintf()
https://notcve.org/view.php?id=CVE-2022-49267
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mmc: core: use sysfs_emit() instead of sprintf() sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool. • https://git.kernel.org/stable/c/659ca56b5415c7a1d05e185c36fad80ba165d063 •

CVE-2022-49264 – exec: Force single empty string when argv is empty

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: exec: Force single empty string when argv is empty Quoting[1] Ariadne Conill: "In several other operating systems, it is a hard requirement that the second argument to execve(2) be the name of a program, thus prohibiting a scenario where argc < 1. POSIX 2017 also recommends this behaviour, but it is not an explicit requirement[2]: The argument arg0 should point to a filename string that is associated with the process being started by one of... • https://git.kernel.org/stable/c/41f6ea5b9aaa28b740d47ffe995a5013211fdbb0 •

CVE-2022-49235 – ath9k_htc: fix uninit value bugs
https://notcve.org/view.php?id=CVE-2022-49235
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: ath9k_htc: fix uninit value bugs Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero w... • https://git.kernel.org/stable/c/fb9987d0f748c983bb795a86f47522313f701a08 •

CVE-2022-49197 – af_netlink: Fix shift out of bounds in group mask calculation
https://notcve.org/view.php?id=CVE-2022-49197
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: af_netlink: Fix shift out of bounds in group mask calculation When a netlink message is received, netlink_recvmsg() fills in the address of the sender. One of the fields is the 32-bit bitfield nl_groups, which carries the multicast group on which the message was received. The least significant bit corresponds to group 1, and therefore the highest group that the field can represent is 32. Above that, the UB sanitizer flags the out-of-bounds ... • https://git.kernel.org/stable/c/f7fa9b10edbb9391bdd4ec8e8b3d621d0664b198 •

CVE-2022-49191 – mxser: fix xmit_buf leak in activate when LSR == 0xff
https://notcve.org/view.php?id=CVE-2022-49191
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mxser: fix xmit_buf leak in activate when LSR == 0xff When LSR is 0xff in ->activate() (rather unlike), we return an error. Provided ->shutdown() is not called when ->activate() fails, nothing actually frees the buffer in this case. Fix this by properly freeing the buffer in a designated label. We jump there also from the "!info->type" if now too. • https://git.kernel.org/stable/c/6769140d304731f0a3b177470a2adb4bacd9036b •

CVE-2022-49180 – LSM: general protection fault in legacy_parse_param
https://notcve.org/view.php?id=CVE-2022-49180
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: LSM: general protection fault in legacy_parse_param The usual LSM hook "bail on fail" scheme doesn't work for cases where a security module may return an error code indicating that it does not recognize an input. In this particular case Smack sees a mount option that it recognizes, and returns 0. A call to a BPF hook follows, which returns -ENOPARAM, which confuses the caller because Smack has processed its data. The SELinux hook incorrectl... • https://git.kernel.org/stable/c/ddcdda888e14ca451b3ee83d11b65b2a9c8e783b •
