CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2022-43945 – kernel: nfsd buffer overflow by RPC message over TCP with garbage data
https://notcve.org/view.php?id=CVE-2022-43945
The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. • http://packetstormsecurity.com/files/171289/Kernel-Live-Patch-Security-Notice-LNS-0092-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f90497a16e434c2211c66e3de8e77b17868382b8 https://security.netapp.com/advisory/ntap-20221215-0006 https://access.redhat.com/security/cve/CVE-2022-43945 https://bugzilla.redhat.com/show_bug.cgi?id=2141752 • CWE-131: Incorrect Calculation of Buffer Size CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-43750
drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-space client to corrupt the monitor's internal memory. El archivo drivers/usb/mon/mon_bin.c en usbmon en el kernel de Linux versiones anteriores a 5.19.15 y versiones 6.x anteriores a 6.0.1, permite que un cliente del espacio de usuario corrompa la memoria interna del monitor An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19.15 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.0.1 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a659daf63d16aa883be42f3f34ff84235c302198 https://github.com/torvalds/linux/commit/a659daf63d16aa883be42f3f34ff84235c302198 https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lists.debian.org/debian-lts-announce/2022/12/msg00034.html https://access.redhat.com/security/cve • CWE-787: Out-of-bounds Write •
