Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftlimit: avoided a possible division error in nftlimitinit divu64 divides an u64 value by an u32 value. nftlimitinit attempts to divide an u64 value by another u64 value; the appropriate math function div64u64 shou...

SUSE CVE-2026-31423

In the Linux kernel, the following vulnerability has been resolved: net/sched: schhfsc: fix divide-by-zero in rtscmin m2sm converts a u32 slope to a u64 scaled value. For large inputs e.g. m1=4000000000, the result can reach 2^32. rtscmin stores the difference of two such u64 values in a u32...

CVE-2026-31423

The CVE-2026-31423 issue affects the Linux kernel’s net/sched sch_hfsc; rtsc_min() can divide by a value derived from the difference of large u64 slopes, risking a divide-by-zero when the difference equals 2^32. The fix widens the internal counter to u64 and replaces do_div() with div64_u64() to ...
