CVSS: -EPSS: %CPEs: 8EXPL: 0CVE-2024-53148 – comedi: Flush partial mappings in error case
https://notcve.org/view.php?id=CVE-2024-53148
In the Linux kernel, the following vulnerability has been resolved: comedi: Flush partial mappings in error case If some remap_pfn_range() calls succeeded before one failed, we still have buffer pages mapped into the userspace page tables when we drop the buffer reference with comedi_buf_map_put(bm). The userspace mappings are only cleaned up later in the mmap error path. Fix it by explicitly flushing all mappings in our VMA on the error path. See commit 79a61cc3fc04 ("mm: avoid leaving partial pfn mappings around in error case"). • https://git.kernel.org/stable/c/ed9eccbe8970f6eedc1b978c157caf1251a896d4 https://git.kernel.org/stable/c/57f048c2d205b85e34282a9b0b0ae177e84c2f44 https://git.kernel.org/stable/c/b9322408d83accc8b96322bc7356593206288c56 https://git.kernel.org/stable/c/8797b7712de704dc231f9e821d8eb3b9aeb3a032 https://git.kernel.org/stable/c/16c507df509113c037cdc0ba642b9ab3389bd26c https://git.kernel.org/stable/c/9b07fb464eb69a752406e78e62ab3a60bfa7b00d https://git.kernel.org/stable/c/c6963a06ce5c61d3238751ada04ee1569663a828 https://git.kernel.org/stable/c/297f14fbb81895f4ccdb0ad25d196786d •
CVSS: -EPSS: %CPEs: 3EXPL: 0CVE-2024-53147 – exfat: fix out-of-bounds access of directory entries
https://notcve.org/view.php?id=CVE-2024-53147
In the Linux kernel, the following vulnerability has been resolved: exfat: fix out-of-bounds access of directory entries In the case of the directory size is greater than or equal to the cluster size, if start_clu becomes an EOF cluster(an invalid cluster) due to file system corruption, then the directory entry where ei->hint_femp.eidx hint is outside the directory, resulting in an out-of-bounds access, which may cause further file system corruption. This commit adds a check for start_clu, if it is an invalid cluster, the file or directory will be treated as empty. • https://git.kernel.org/stable/c/a0120d6463368378539ef928cf067d02372efb8c https://git.kernel.org/stable/c/3ddd1cb2b458ff6a193bc845f408dfff217db29e https://git.kernel.org/stable/c/184fa506e392eb78364d9283c961217ff2c0617b •

https://notcve.org/view.php?id=CVE-2024-53146
In the Linux kernel, the following vulnerability has been resolved: NFSD: Prevent a potential integer overflow If the tag length is >= U32_MAX - 3 then the "length + 4" addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decode_cb_compound4res() does not have to perform arithmetic on the unsafe length value. • https://git.kernel.org/stable/c/745f7ce5a95e783ba62fe774325829466aec2aa8 https://git.kernel.org/stable/c/90adbae9dd158da8331d9fdd32077bd1af04f553 https://git.kernel.org/stable/c/3c5f545c9a1f8a1869246f6f3ae8c17289d6a841 https://git.kernel.org/stable/c/842f1c27a1aef5367e535f9e85c8c3b06352151a https://git.kernel.org/stable/c/de53c5305184ca1333b87e695d329d1502d694ce https://git.kernel.org/stable/c/dde654cad08fdaac370febb161ec41eb58e9d2a2 https://git.kernel.org/stable/c/084f797dbc7e52209a4ab6dbc7f0109268754eb9 https://git.kernel.org/stable/c/ccd3394f9a7200d6b088553bf38e68862 •

https://notcve.org/view.php?id=CVE-2024-53241
In the Linux kernel, the following vulnerability has been resolved: x86/xen: don't do PV iret hypercall through hypercall page Instead of jumping to the Xen hypercall page for doing the iret hypercall, directly code the required sequence in xen-asm.S. This is done in preparation of no longer using hypercall page at all, as it has shown to cause problems with speculation mitigations. This is part of XSA-466 / CVE-2024-53241. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: x86/xen: no realizar la hiperllamada de PV iret a través de la página de hiperllamada En lugar de saltar a la página de hiperllamada de Xen para realizar la hiperllamada iret, codificar directamente la secuencia requerida en xen-asm.S. Esto se hace como preparación para no utilizar más la página de hiperllamada, ya que se ha demostrado que causa problemas con las mitigaciones de especulación.
