CVE-2024-26704 – ext4: fix double-free of blocks due to wrong extents moved_len
https://notcve.org/view.php?id=CVE-2024-26704
03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: ext4: fix double-free of blocks due to wrong extents moved_len In ext4_move_extents(), moved_len is only updated when all moves are successfully executed, and only discards orig_inode and donor_inode preallocations when moved_len is not zero. When the loop fails to exit after successfully moving some extents, moved_len is not updated and remains at 0, so it does not discard the preallocations. If the moved extents overlap with the prealloca... • https://git.kernel.org/stable/c/fcf6b1b729bcd23f2b49a84fb33ffbb44712ee6a • CWE-415: Double Free •
CVE-2024-26703 – tracing/timerlat: Move hrtimer_init to timerlat_fd open()
https://notcve.org/view.php?id=CVE-2024-26703
03 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: tracing/timerlat: Move hrtimer_init to timerlat_fd open() Currently, the timerlat's hrtimer is initialized at the first read of timerlat_fd, and destroyed at close(). It works, but it causes an error if the user program open() and close() the file without reading. Here's an example: # echo NO_OSNOISE_WORKLOAD > /sys/kernel/debug/tracing/osnoise/options # echo timerlat > /sys/kernel/debug/tracing/current_tracer # cat <
