https://notcve.org/view.php?id=CVE-2024-36881
In the Linux kernel, the following vulnerability has been resolved: mm/userfaultfd: reset ptes when close() for wr-protected ones Userfaultfd unregister includes a step to remove wr-protect bits from all the relevant pgtable entries, but that only covered an explicit UFFDIO_UNREGISTER ioctl, not a close() on the userfaultfd itself. Cover that too. This fixes a WARN trace. The only user visible side effect is the user can observe leftover wr-protect bits even if the user close()ed on an userfaultfd when releasing the last reference of it. However hopefully that should be harmless, and nothing bad should happen even if so. This change is now more important after the recent page-table-check patch we merged in mm-unstable (446dd9ad37d0 ("mm/page_table_check: support userfault wr-protect entries")), as we'll do sanity check on uffd-wp bits without vma context. So it's better if we can 100% guarantee no uffd-wp bit leftovers, to make sure each report will be valid. • https://git.kernel.org/stable/c/f369b07c861435bd812a9d14493f71b34132ed6f https://git.kernel.org/stable/c/3e2747c3ddfa717697c3cc2aa6ab989e48d6587d https://git.kernel.org/stable/c/377f3a9a3d032a52325a5b110379a25dd1ab1931 https://git.kernel.org/stable/c/8d8b68a5b0c9fb23d37df06bb273ead38fd5a29d https://git.kernel.org/stable/c/c88033efe9a391e72ba6b5df4b01d6e628f4e734 https://access.redhat.com/security/cve/CVE-2024-36881 https://bugzilla.redhat.com/show_bug.cgi?id=2284277 • CWE-281: Improper Preservation of Permissions •

https://notcve.org/view.php?id=CVE-2024-36031
In the Linux kernel, the following vulnerability has been resolved: keys: Fix overwrite of key expiration on instantiation The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expiry is only called when the pre-parser sets a specific expiry. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: claves: se corrige la sobrescritura de la caducidad de la clave al crear instancias. El tiempo de caducidad de una clave se sobrescribe incondicionalmente durante la creación de instancias, y de forma predeterminada se vuelve permanente. • https://git.kernel.org/stable/c/97be1e865e70e5a0ad0a5b5f5dca5031ca0b53ac https://git.kernel.org/stable/c/2552b32b0b349df160a509fe49f5f308cb922f2b https://git.kernel.org/stable/c/791d5409cdb974c31a1bc7a903ea729ddc7d83df https://git.kernel.org/stable/c/afc360e8a1256acb7579a6f5b6f2c30b85b39301 https://git.kernel.org/stable/c/39299bdd2546688d92ed9db4948f6219ca1b9542 https://git.kernel.org/stable/c/ad2011ea787928b2accb5134f1e423b11fe80a8a https://git.kernel.org/stable/c/ed79b93f725cd0da39a265dc23d77add1527b9be https://git.kernel.org/stable/c/e4519a016650e952ad9eb27937f8c447d • CWE-324: Use of a Key Past its Expiration Date CWE-665: Improper Initialization •
