A use-after-free flaw was found in the Linux kernel in log_replay in fs/ntfs3/fslog.c in the NTFS journal. This flaw allows a local attacker to crash the system and leads to a kernel information leak problem. Se encontró un defecto de uso de memoria previamente liberada en el kernel de Linux en la función log_replay en el archivo fs/ntfs3/fslog.c en el diario NTFS. Este fallo permite a un atacante local bloquear el sistema y conlleva a un problema de filtrado de información del kernel • https://bugzilla.redhat.com/show_bug.cgi?id=2092542 https://security.netapp.com/advisory/ntap-20230120-0001 • CWE-416: Use After Free •
CVSS: 6.7EPSS: 0%CPEs: 8EXPL: 0CVE-2021-33655 – kernel: malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory
https://notcve.org/view.php?id=CVE-2021-33655
When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. Cuando son enviados datos maliciosos al kernel mediante ioctl cmd FBIOPUT_VSCREENINFO, el kernel escribirá memoria fuera de límites An out-of-bounds write flaw was found in the Linux kernel’s framebuffer-based console driver functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data. This flaw allows a local user to crash or potentially escalate their privileges on the system. • http://www.openwall.com/lists/oss-security/2022/07/19/2 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=086ff84617185393a0bbf25830c4f36412a7d3f4 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://www.debian.org/security/2022/dsa-5191 https://access.redhat.com/security/cve/CVE-2021-33655 https://bugzilla.redhat.com/show_bug.cgi?id=2108691 • CWE-787: Out-of-bounds Write •

Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740). Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742).
