Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: RISCV: Sanitizing syscall table indexing under speculation The syscall number is a user-controlled value used to index into the syscall table. Use arrayindexnospec to clamp this value after the bounds check, to prevent speculativ...

GHSA-F2R5-5M7W-P5CX opentelemetry-ebpf-profiler: Unprivileged process can trigger a denial of service on the ebpf-profiler agent

Summary An unprivileged process can easily trigger the processPIDEvents goroutine to be blocked indefinitely, preventing the goroutine from analyzing any new ELF file. The goroutine stays blocked in the openat2 syscall forever and the profiler can no longer work properly, it is a denial of servic...
