https://notcve.org/view.php?id=CVE-2021-28950
An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A "stall on CPU" can occur because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. Se detectó un problema en el archivo fs/fuse/fuse_i.h en el kernel de Linux versiones anteriores a 5.11.8. Un "stall on CPU" puede ocurrir porque un bucle de reintento encuentra continuamente el mismo inode malo, también se conoce como CID-775c5033a0d1 A denial of service in the kernel side of the FUSE functionality can allow a local system to create a denial of service. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.11.8 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=775c5033a0d164622d9d10dd0f0a5531639ed3ed https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FB6LUXPEIRLZH32YXWZVEZAD4ZL6SDK2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-834: Excessive Iteration CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (deadlock) because exit may be waiting to park a SQPOLL thread, but concurrently that SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25. Se detectó un problema en el archivo fs/io_uring.c en el kernel de Linux versiones hasta 5.11.8. Permite a atacantes causar una denegación de servicio (deadlock) porque la salida puede estar esperando para estacionar un hilo SQPOLL, pero al mismo tiempo ese hilo SQPOLL está esperando una señal para comenzar, también se conoce como CID-3ebba796fa25 • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3ebba796fa251d042be42b929a2d916ee5c34a49 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4VCKIOXCOZGXBEZMO5LGGV5MWCHO6FT3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PTRNPQTZ4GVS46SZ4OBXY5YDOGVPSTGQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/T2S3I4SLRNRUQDOFYUS6IUAZMQNMPNLG https://security.netapp.com/advisory/ntap-20210430-0003 • CWE-667: Improper Locking •

rtw_wx_set_scan in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the Linux kernel through 5.11.6 allows writing beyond the end of the ->ssid[] array. NOTE: from the perspective of kernel.org releases, CVE IDs are not normally used for drivers/staging/* (unfinished work); however, system integrators may have situations in which a drivers/staging issue is relevant to their own customer base. La función rtw_wx_set_scan en el archivo drivers/staging/rtl8188eu/os_dep/ioctl_linux.c en el kernel de Linux versiones hasta 5.11.6, permite escribir más allá del final de la matriz -)ssid[]. NOTA: desde la perspectiva de las versiones de kernel.org, las ID de CVE no se usan normalmente para drivers/staging/* (trabajo sin terminar); sin embargo, los integradores de sistemas pueden tener situaciones en las que un problema de drivers/staging sea relevante para su propia base de clientes • http://www.openwall.com/lists/oss-security/2022/11/18/1 http://www.openwall.com/lists/oss-security/2022/11/21/2 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=74b6b20df8cfe90ada777d621b54c32e69e27cd7 https://lists.debian.org/debian-lts-announce/2021/03/msg00035.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TJPVQZPY3DHPV5I3IVNMSMO6D3PKZISX https:/&#x • CWE-787: Out-of-bounds Write •
