Summary
Moderate: kernel security, bug fix, and enhancement update
Details
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
- off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516)
- race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558)
- use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640)
- memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c (CVE-2021-30002)
- smb2_ioctl_query_info NULL Pointer Dereference (CVE-2022-0168)
- NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617)
- swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854)
- uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016)
- race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048)
- use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055)
- use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184)
- NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852)
- buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078)
- nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)
- openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)
- use-after-free when psi trigger is destroyed while being polled (CVE-2022-2938)
- net/packet: slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)
- possible to use the debugger to write zero into a location of choice (CVE-2022-21499)
- Spectre-BHB (CVE-2022-23960)
- Post-barrier Return Stack Buffer Predictions (CVE-2022-26373)
- memory leak in drivers/hid/hid-elo.c (CVE-2022-27950)
- double free in ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c (CVE-2022-28390)
- use after free in SUNRPC subsystem (CVE-2022-28893)
- use-after-free due to improper update of reference count in net/sched/cls_u32.c (CVE-2022-29581)
- DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c (CVE-2022-36946)
- nfs_atomic_open() returns uninitialized data instead of ENOTDIR (CVE-2022-24448)

CVE-2022-23960 (GCVE-0-2022-23960)
Vulnerability from cvelistv5 – Published: 2022-03-12 23:57 – Updated: 2024-08-03 03:59
VLAI?
EPSS
Summary
Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information.
Severity ?
No CVSS data available.

CVE-2022-2639 (GCVE-0-2022-2639)
Vulnerability from cvelistv5 – Published: 2022-09-01 20:32 – Updated: 2024-08-03 00:46
VLAI?
EPSS
Summary
An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.
Severity ?
No CVSS data available.

CVE-2022-24448 (GCVE-0-2022-24448)
Vulnerability from cvelistv5 – Published: 2022-02-04 19:45 – Updated: 2024-08-03 04:13
VLAI?
EPSS
Summary
An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.
Severity ?
No CVSS data available.
