Astra Linux - уязвимость в linux-6.1

In the Linux kernel, the following vulnerability has been resolved: iommufd: Do not cause an overflow during division for dirty tracking. If pgshift is 63, then BITSPERTYPEbitmap-bitmap pgsize will result in an overflow to 0. This triggers a division by 0. In this case, the index should simply be...

CVE-2023-54251

The CVE-2023-54251 issue is in the Linux kernel net/sched/taprio path, where TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME was cast inconsistently (s64 cycle_time vs s32 divisor) leading to a potential divide-by-zero in div_s64_rem() called from get_cycle_time_elapsed(). The fix preserves s64 for cycle_time t...
