kernel: use-after-free due to improper update of reference count in net/sched/cls_u32.c

A use-after-free flaw was found in u32change in net/sched/clsu32.c in the network subcomponent of the Linux kernel. This flaw allows a local attacker to crash the system, cause a privilege escalation, and leak kernel information...

CVE-2022-23090 AIO credential reference count leak

The aioaqueue function, used by the liolistio system call, fails to release a reference to a credential in an error case. An attacker may cause the reference count to overflow, leading to a use after free UAF...

CVE-2022-23090

The CVE-2022-23090 issue concerns the FreeBSD aio_aqueue function, used by the lio_listio system call, which fails to release a credential reference in an error path. This reference-count leak can allow an attacker to overflow the reference count, resulting in a use-after-free (UAF) condition. Th...

kernel: xfrm_expand_policies() in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice

A flaw was found in the Linux kernel’s IP framework for transforming packets XFRM subsystem. An error while resolving policies in xfrmbundlelookup causes the refcount to drop twice, leading to a possible crash and a denial of service...

RLSA-2024:0134 Important: kernel-rt security update

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Linux Kernel Denial of Service Vulnerability (CNVD-2024-14766)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A denial of service attack vulnerability exists in the Linux Kernel. The vulnerability is due to a memory leak found in ctnetlinkcreateconntrack in...

DEBIAN-CVE-2023-6270

A flaw was found in the ATA over Ethernet AoE driver in the Linux kernel. The aoecmdcfgpkts function improperly updates the refcnt on struct netdevice, and a use-after-free can be triggered by racing between the free on the struct and the access through the skbtxq global queue. This could lead to...
