CVE-2022-1184

The Linux Kernel, the operating system core itself.

Security Fix(es):

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.(CVE-2022-1184)

An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur.(CVE-2022-39842)

A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or member of the audio group) could use this flaw to crash the system, resulting in a denial of service condition(CVE-2022-3303)

An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured.(CVE-2022-2663)

drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free if a physically proximate attacker removes a USB device while calling open(), aka a race condition between ufx_ops_open and ufx_usb_disconnect.(CVE-2022-41849)

In binder_inc_ref_for_node of binder.c, there is a possible way to corrupt memory due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-239630375References: Upstream kernel(CVE-2022-20421)

In emulation_proc_handler of armv8_deprecated.c, there is a possible way to corrupt memory due to a race condition.

User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-237540956References: Upstream kernel(CVE-2022-20422)

A vulnerability classified as problematic has been found in Linux Kernel. This affects the function fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-210357 was assigned to this vulnerability.(CVE-2022-3435)

An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c.(CVE-2022-41674)

roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report->value is in progress.(CVE-2022-41850)

mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.(CVE-2022-42703)

A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.x before 5.19.16 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code.(CVE-2022-42719)

Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-free conditions to potentially execute code.(CVE-2022-42720)

A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in turn, potentially execute code.(CVE-2022-42721)

The SUSE Linux Enterprise 12 SP2 kernel was updated.

The following security bugs were fixed:

• CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c vulnerability in the Linux kernel (bnc#1198031).
• CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c vulnerability in the Linux kernel (bnc#1198032).
• CVE-2018-20784: Fixed a denial of service (infinite loop in update_blocked_averages) by mishandled leaf cfs_rq in kernel/sched/fair.c (bnc#1126703).
• CVE-2018-7755: Fixed an issue in the fd_locked_ioctl function in drivers/block/floppy.c. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR (bnc#1084513).
• CVE-2020-10769: Fixed a buffer over-read flaw in the IPsec Cryptographic algorithm's module. This flaw allowed a local attacker with user privileges to cause a denial of service. (bnc#1173265)
• CVE-2021-28688: Fixed XSA-365 that includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died, leaving around zombie domains (bnc#1183646).

• CVE-2017-13695: Fixed a bug that caused a stack dump allowing local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted ACPI table. (bnc#1055710)
• CVE-2022-1729: Fixed a sys_perf_event_open() race condition against self (bsc#1199507).
• CVE-2022-21499: Reinforce the kernel lockdown feature, until now it's been trivial to break out of it with kgdb or kdb. (bsc#1199426)
• CVE-2022-1652: Fixed a statically allocated error counter inside the floppy kernel module (bsc#1199063).
• CVE-2022-1734: Fixed a r/w use-after-free when non synchronized between cleanup routine and firmware download routine. (bnc#1199605)
