DATE CVE VULNERABILITY TITLE RISK
2023-12-19 CVE-2023-6931 Out-of-bounds Write vulnerability in multiple products
A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.

2023-12-19 CVE-2023-6932 Use After Free vulnerability in Linux Kernel
A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread. We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.

2023-12-18 CVE-2023-6817 Use After Free vulnerability in Linux Kernel
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free. We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.

2023-12-09 CVE-2023-50431 Unspecified vulnerability in Linux Kernel
sec_attest_info in drivers/accel/habanalabs/common/habanalabs_ioctl.c in the Linux kernel through 6.6.5 allows an information leak to user space because info->pad0 is not initialized.

2023-11-14 CVE-2023-6111 Use After Free vulnerability in Linux Kernel
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times. We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630.

2023-10-25 CVE-2023-5717 Out-of-bounds Write vulnerability in Linux Kernel
A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer. We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06.
