A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086) In rds_recv_track_latency in net/rds/af_rds.c in the Linux kernel up to and including 6.7.1, there is an off-by-one error for an RDS_MSG_RX_DGRAM_TRACE_MAX comparison, resulting in out-of-bounds access. (CVE-2024-23849)

A Linux privilege-escalation proof-of-concept exploit has been published that, according to the bug hunter who developed it, typically works effortlessly on kernel versions between at least 5.14 and 6.6.14. Running the exploit as a normal user on a vulnerable machine will grant you root access to the box, allowing you to do whatever you want on it. This can be used by rogue insiders or malware already on a computer to cause further damage and problems. This affects Debian, Ubuntu, Red Hat,...
