--- title: "CVE-2026-89786\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2026-89786?format=md keywords: index, follow --- # CVE-2026-89786 Publication date 17 September 2026 Last updated 17 September 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description In the Linux kernel, the following vulnerability has been resolved: ext4: fix out-of-bounds read in ext4\_read\_inline\_dir() ext4\_read\_inline\_dir() can read a dirent header past the end of its inline buffer, triggering a slab-out-of-bounds read during getdents64(): BUG: KASAN: slab-out-of-bounds in \_\_ext4\_check\_dir\_entry Read of size 2 at addr ffff88800f3dd23c by task exploit/148 ... \_\_ext4\_check\_dir\_entry ext4\_read\_inline\_dir iterate\_dir The dirent payload lives in a buffer of exactly inline\_size bytes: dir\_buf = kmalloc(inline\_size, GFP\_NOFS); but iteration runs in a position space extra\_offset bytes larger (extra\_size = extra\_offset + inline\_size) so the synthetic "." and ".." land at their block-dir offsets. A dirent is formed at "dir\_buf + pos - extra\_offset", yet the ext4\_check\_dir\_entry() length argument uses the larger extra\_size. A position whose dirent header would extend past extra\_size is therefore accepted, and the rescan loop's rec\_len probe and ext4\_check\_dir\_entry() dereference de->rec\_len before the entry is rejected. Reject a position whose minimum-size dirent header would not fit within extra\_size before forming de, in both the rescan and main loops, and pass inline\_size rather than extra\_size to ext4\_check\_dir\_entry() so the length check matches the physical buffer. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 26.04 LTS resolute |
