An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931. Se detectó un problema en el kernel de Linux versiones hasta 5.11.3, como es usada con Xen PV. • http://www.openwall.com/lists/oss-security/2021/03/05/1 http://xenbits.xen.org/xsa/advisory-367.html https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2991397d23ec597405b116d96de3813420bdcbc3 https://lists.debian.org/debian-lts-announce/2021/03/msg00010.html https://lists.debian.org/debian-lts-announce/2021/03/msg00035.html https://security.netapp.com/advisory/ntap-20210409-0001 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 1CVE-2021-26708 – kernel: race conditions caused by wrong locking in net/vmw_vsock/af_vsock.c
https://notcve.org/view.php?id=CVE-2021-26708
A local privilege escalation was discovered in the Linux kernel before 5.10.13. Multiple race conditions in the AF_VSOCK implementation are caused by wrong locking in net/vmw_vsock/af_vsock.c. The race conditions were implicitly introduced in the commits that added VSOCK multi-transport support. Se detectó una escalada de privilegios local en el kernel de Linux versiones anteriores a 5.10.13. Múltiples condiciones de carrera en la implementación de AF_VSOCK son causadas mediante un bloqueo incorrecto en el archivo net/vmw_vsock / af_vsock.c. • https://github.com/azpema/CVE-2021-26708 http://www.openwall.com/lists/oss-security/2021/02/05/6 http://www.openwall.com/lists/oss-security/2021/04/09/2 http://www.openwall.com/lists/oss-security/2022/01/25/14 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10.13 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c518adafa39f37858697ac9309c6cf1805581446 https://security.netapp.com/advisory/ntap-20210312-0008 https://www.openwall • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking •
