CVSS: 7.8EPSS: 0%CPEs: 26EXPL: 0CVE-2022-28893 – kernel: use after free in SUNRPC subsystem
https://notcve.org/view.php?id=CVE-2022-28893
The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. El subsistema SUNRPC en el kernel de Linux versiones hasta 5.17.2, puede llamar a xs_xprt_free antes de asegurarse de que los sockets están en el estado deseado A use-after-free flaw was found in the Linux kernel’s net/sunrpc/xprt.c function in the Remote Procedure Call (SunRPC) protocol. This flaw allows a local attacker to crash the system, leading to a kernel information leak issue. • http://www.openwall.com/lists/oss-security/2022/04/11/3 http://www.openwall.com/lists/oss-security/2022/04/11/4 http://www.openwall.com/lists/oss-security/2022/04/11/5 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1a3b1bba7c7a5eb8a11513cf88427cb9d77bc60a https://security.netapp.com/advisory/ntap-20220526-0002 https://www.debian.org/security/2022/dsa-5161 https://access.redhat.com/security/cve/CVE-2022-28893 https://bugzilla.redhat.com/s • CWE-416: Use After Free •

ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free. La función ems_usb_start_xmit en el archivo drivers/net/can/usb/ems_usb.c en el kernel de Linux versiones hasta 5.17.1, presenta una doble liberación A double-free flaw was found in the Linux kernel in the ems_usb_start_xmit function. This flaw allows an attacker to create a memory leak and corrupt the underlying data structure by calling free more than once. • https://github.com/torvalds/linux/commit/c70222752228a62135cee3409dccefd494a24646 https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6IHHC455LMSJNG4CSZ5CEAHYWY2DE5YW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LAWC35TO642FOP3UCA3C6IF7NAUFOVZ6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XFMPUI3WI4U2F7ONHRW36WDY4ZE7LGGT https://security.netapp.com/advis • CWE-415: Double Free •
CVSS: 8.2EPSS: 0%CPEs: 71EXPL: 2CVE-2018-25032 – zlib: A flaw found in zlib when compressing (not decompressing) certain inputs
https://notcve.org/view.php?id=CVE-2018-25032
zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. zlib versiones anteriores a 1.2.12 permite la corrupción de memoria al desinflar (es decir, al comprimir) si la entrada tiene muchas coincidencias distantes An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application. • http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2022/03/25/2 http://www.openwall.com/lists/oss-security/2022/03/26/1 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://github.com/madler/zlib/commit/5c44459c3b28a9bd3283aaceab7c615f8020c531 https://github.com/madler/zlib/compare/v1.2.11...v1.2.12 https://github.com& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
