CVSS: 9.8EPSS: 3%CPEs: 12EXPL: 1CVE-2023-5178 – Kernel: use after free in nvmet_tcp_free_crypto in nvme
https://notcve.org/view.php?id=CVE-2023-5178
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation. Se encontró una vulnerabilidad de use-after-free en drivers/nvme/target/tcp.c` en `nvmet_tcp_free_crypto` debido a un error lógico en el subsistema NVMe-oF/TCP en el kernel de Linux. Este problema puede permitir que un usuario malintencionado cause un problema de use-after-free y double-free, lo que puede permitir la ejecución remota de código o provocar una escalada de privilegios locales en caso de que el atacante ya tenga privilegios locales. • https://github.com/rockrid3r/CVE-2023-5178 https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7548 https://access.redhat.com/errata/RHSA-2023:7549 https://access.redhat.com/errata/RHSA-2023:7551 https://access.redhat.com/errata/RHSA-2023:7554 https://access.redhat.com/errata/RHSA-2023:7557 https://access.redhat.com/errata/RHSA-2023 • CWE-416: Use After Free •
CVSS: 6.5EPSS: 0%CPEs: 9EXPL: 0CVE-2023-36054 – krb5: Denial of service through freeing uninitialized pointer
https://notcve.org/view.php?id=CVE-2023-36054
lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. A vulnerability was found in the _xdr_kadm5_principal_ent_rec() function in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (krb5). This issue occurs due to lack of validation in the relationship between n_key_data and the key_data array count, leading to the freeing of uninitialized pointers. • https://github.com/krb5/krb5/commit/ef08b09c9459551aabbe7924fb176f1583053cdd https://github.com/krb5/krb5/compare/krb5-1.20.1-final...krb5-1.20.2-final https://github.com/krb5/krb5/compare/krb5-1.21-final...krb5-1.21.1-final https://lists.debian.org/debian-lts-announce/2023/10/msg00031.html https://security.netapp.com/advisory/ntap-20230908-0004 https://web.mit.edu/kerberos/www/advisories https://access.redhat.com/security/cve/CVE-2023-36054 https://bugzilla.redhat.com&#x • CWE-824: Access of Uninitialized Pointer •
