Threats tagged 'ghsa-gj5h-7fq5-56p5'

A potential deadlock vulnerability in the Linux kernel's f2fs filesystem was fixed. The issue caused a kernel hang due to a deadloop in the prepare_compress_overwrite() function when handling IO errors during compressed cluster page reads. This could block writeback tasks and cause system instability. The fix adds error detection and handling to prevent the deadloop. The vulnerability affects specific Linux kernel versions listed and has a medium severity rating with no confidentiality or integrity impact but availability impact due to hangs.
