CVE-2025-71269

EPSS:0.02%probability of exploitation in 30 daysPercentile:4.5th

Official Description

In the Linux kernel, the following vulnerability has been resolved:

btrfs: do not free data reservation in fallback from inline due to -ENOSPC

If we fail to create an inline extent due to -ENOSPC, we will attempt to

go through the normal COW path, reserve an extent, create an ordered

extent, etc. However we were always freeing the reserved qgroup data,

which is wrong since we will use data. Fix this by freeing the reserved

qgroup data in __cow_file_range_inline() only if we are not doing the

fallback (ret is <= 0).

Technical Analysis

CVE-2025-71269 requires local access, meaning attackers must already have a foothold on the target system.
