Detail
| In the Linux kernel, the following vulnerability has been resolved: btrfs: prevent copying too big compressed lzo segment Compressed length can be corrupted to be a lot larger than memory we have allocated for buffer. This will cause memcpy in copy_compressed_segment to write outside of allocated memory. This mostly results in stuck read syscall but sometimes when using btrfs send can get #GP kernel: general protection fault, probably for non-canonical address 0x841551d5c1000: 0000 [#1] PREEMPT SMP NOPTI |
