CVE-2023-54062 (GCVE-0-2023-54062)

Vulnerability from cvelistv5 – Published: 2025-12-24 12:23 – Updated: 2026-01-05 10:33

Title

ext4: fix invalid free tracking in ext4_xattr_move_to_block()

Summary

In the Linux kernel, the following vulnerability has been resolved: ext4: fix invalid free tracking in ext4_xattr_move_to_block() In ext4_xattr_move_to_block(), the value of the extended attribute which we need to move to an external block may be allocated by kvmalloc() if the value is stored in an external inode. So at the end of the function the code tried to check if this was the case by testing entry->e_value_inum. However, at this point, the pointer to the xattr entry is no longer valid, because it was removed from the original location where it had been stored. So we could end up calling kvfree() on a pointer which was not allocated by kvmalloc(); or we could also potentially leak memory by not freeing the buffer when it should be freed. Fix this by storing whether it should be freed in a separate variable.

So at the end\nof the function the code tried to check if this was the case by\ntesting entry-\u003ee_value_inum.\n\nHowever, at this point, the pointer to the xattr entry is no longer\nvalid, because it was removed from the original location where it had\nbeen stored.  So we could end up calling kvfree() on a pointer which\nwas not allocated by kvmalloc(); or we could also potentially leak\nmemory by not freeing the buffer when it should be freed.  Fix this by\nstoring whether it should be freed in a separate variable."
