CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-26832 – mm: zswap: fix missing folio cleanup in writeback race path
https://notcve.org/view.php?id=CVE-2024-26832
In the Linux kernel, the following vulnerability has been resolved: mm: zswap: fix missing folio cleanup in writeback race path In zswap_writeback_entry(), after we get a folio from __read_swap_cache_async(), we grab the tree lock again to check that the swap entry was not invalidated and recycled. If it was, we delete the folio we just added to the swap cache and exit. However, __read_swap_cache_async() returns the folio locked when it is newly allocated, which is always true for this path, and the folio is ref'd. Make sure to unlock and put the folio before returning. This was discovered by code inspection, probably because this path handles a race condition that should not happen often, and the bug would not crash the system, it will only strand the folio indefinitely. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mm: zswap: corrige la limpieza de folio faltante en la ruta de carrera de escritura diferida En zswap_writeback_entry(), después de obtener un folio de __read_swap_cache_async(), tomamos el bloqueo del árbol nuevamente para verificar que el intercambio la entrada no fue invalidada y reciclada. Si así fuera, eliminamos la publicación que acabamos de agregar al caché de intercambio y salimos. • https://git.kernel.org/stable/c/2cab13f500a6333bd2b853783ac76be9e4956f8a https://git.kernel.org/stable/c/04fc7816089c5a32c29a04ec94b998e219dfb946 https://git.kernel.org/stable/c/ba700ea13bf0105a4773c654f7d3bef8adb64ab2 https://git.kernel.org/stable/c/14f1992430ef9e647b02aa8ca12c5bcb9a1dffea https://git.kernel.org/stable/c/6156277d1b26cb3fdb6fcbf0686ab78268571644 https://git.kernel.org/stable/c/e2891c763aa2cff74dd6b5e978411ccf0cf94abe https://git.kernel.org/stable/c/e3b63e966cac0bf78aaa1efede1827a252815a1d •
