EUVD-2026-55529

In the Linux kernel, the following vulnerability has been resolved: iomap: fix out-of-bounds bitmapset with zero-length range ifssetrangedirty and ifssetrangeuptodate compute lastblk as off + len - 1 iblkbits. When off is 0 and len is 0, the unsigned subtraction underflows to SIZEMAX, producing a...

CVE-2026-68145

Summary: The CVE affects the Linux kernel iomap path, specifically the functions ifs_set_range_dirty() and ifs_set_range_uptodate() . The root cause is the calculation of the last block as (off + len - 1) >> i_blkbits. When off is 0 and len is 0, unsigned subtraction underflows to SIZE_MAX,...
