In the Linux kernel, the following vulnerability has been resolved: ext4: fix BUG in ext4mbnewinodepa due to overflow When we calculate the end position of ext4freeextent, this position may be exactly where ext4lblkt i.e. uint overflows. For example, if acgex.felogical is 4294965248 and...

CVE-2023-54069

CVE-2023-54069 relates to the Linux kernel ext4 allocator (mballoc). The issue is an overflow in ext4_mb_new_inode_pa() that can occur when computing the end position of ext4_free_extent, potentially overflowing ext4_lblk_t (uint). The fix, as described in the publicly provided documents, refacto...
