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 •

A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an attacker with a local account to leak information about kernel internal addresses. The highest threat from this vulnerability is to confidentiality. Se encontró un fallo en el kernel de Linux en versiones anteriores a 5.4.92 en el protocolo BPF. Este fallo permite a un atacante con una cuenta local filtrar información sobre las direcciones internas del kernel. • https://bugzilla.redhat.com/show_bug.cgi?id=1923636 https://access.redhat.com/security/cve/CVE-2021-20239 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-822: Untrusted Pointer Dereference •

A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver software. The impact of this issue is lessened by the fact that the default permissions on the floppy device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw. Se encontró una condición de carrera en la implementación del kernel de Linux del software manejador del controlador de la unidad de disquete. • https://bugzilla.redhat.com/show_bug.cgi?id=1932150 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a0c80efe5956ccce9fe7ae5c78542578c07bc20a • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

A flaw was found in the Linux kernel in versions prior to 5.10. A violation of memory access was found while detecting a padding of int3 in the linking state. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

An out-of-bounds access flaw was found in the Linux kernel's implementation of the eBPF code verifier in the way a user running the eBPF script calls dev_map_init_map or sock_map_alloc. This flaw allows a local user to crash the system or possibly escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo de acceso fuera de límites en la implementación del comprobador de código eBPF en el kernel de Linux, en la manera en que un usuario que ejecuta el script eBPF llama a las funciones dev_map_init_map o sock_map_alloc. Este fallo permite a un usuario local bloquear el sistema o posiblemente escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1923816 https://lore.kernel.org/bpf/CACAyw99bEYWJCSGqfLiJ9Jp5YE1ZsZSiJxb4RFUTwbofipf0dA%40mail.gmail.com/T/#m8929643e99bea9c18ed490a7bc2591145eac6444 https://security.netapp.com/advisory/ntap-20210409-0006 • CWE-20: Improper Input Validation CWE-190: Integer Overflow or Wraparound •
