Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: s390/syscalls: Added a spectre boundary for the syscall dispatch table. The s390 syscall number is directly controlled by the user space, but there is no arrayindexnospec boundary to prevent access beyond the syscall function...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: schedext: Fixed stale direct dispatch state in ddspdsqid @p-scx.ddspdsqid can be left set non-SCXDSQINVALID, causing a spurious warning in markdirectdispatch when the next wakeup’s ops.selectcpu calls scxbpfdsqinsert. For example...

Astra Linux - уязвимость в linux, linux-5.10, linux-5.15, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Whitelist slab/slub objects for copying to userspace. Reading the dispatch trace log from /sys/kernel/debug/powerpc/dtl/cpu- results in a bug when the CONFIGHARDENEDUSERCOPY configuration is enabled, as shown...

OverrideFuzz: Semantic-Aware Grammar Fuzzing for Script-Runtime Vulnerabilities

Script-language runtimes such as Python, Lua, and JavaScript are widely deployed in security sensitive contexts, yet they remain difficult to test because valid inputs must satisfy syntax, dynamic type constraints, and object-level semantics. Existing grammar and reflection-based fuzzers improve...
