Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftables: prevented nfskbduplicated corruption. syzbot found that nfdupipv4 or nfdupipv6 might write the nfskbduplicated variable in an unsafe manner 1. Disabling preemption, as suggested by splat, is not sufficient...

CVE-2024-49952

The CVE-2024-49952 vulnerability affects the Linux kernel nf_tables/netfilter path, caused by unsafe writes to per-CPU nf_skb_duplicated in nf_dup_ipv4()/nf_dup_ipv6() when preemption is enabled. The issue arises because __this_cpu_write() is used in preemptible code, risking corruption of the pe...
