A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc. Se detectó una condición de carrera en la función get_old_root en el archivo fs/btrfs/ctree.c en el kernel de Linux versiones hasta 5.11.8. Permite a atacantes causar una denegación de servicio (BUG) debido a una falta de bloqueo en un búfer de extensión antes de una operación de clonación, también se conoce como CID-dbcc7d57bffc • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dbcc7d57bffc0c8cac9dac11bec548597d59a6a5 https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html 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& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

An issue was discovered in the Linux kernel through 5.11.8. The sound/soc/qcom/sdm845.c soundwire device driver has a buffer overflow when an unexpected port ID number is encountered, aka CID-1c668e1c0a0f. (This has been fixed in 5.12-rc4.) Se detectó un problema en el kernel de Linux versiones hasta 5.11.8. El controlador de dispositivo soundwire del archivo sound/soc/qcom/sdm845.c presenta un desbordamiento del búfer cuando es encontrado un número de identificación de puerto no previsto, también se conoce como CID-1c668e1c0a0f. • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1c668e1c0a0f74472469cd514f40c9012b324c31 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://lore.kernel.org/alsa-devel/20210309142129.14182-2-sri • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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 •
