loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.
CVE-2021-40042 1 Huawei 8 Cloudengine 12800, Cloudengine 12800 Firmware, Cloudengine 5800 and 5 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
There is a release of invalid pointer vulnerability in some Huawei products, successful exploit may cause the process and service abnormal. Affected product versions include: CloudEngine 12800 V200R019C10SPC800, V200R019C10SPC900; CloudEngine 5800 V200R019C10SPC800, V200R020C00SPC600; CloudEngine 6800 versions V200R019C10SPC800, V200R019C10SPC900, V200R020C00SPC600, V300R020C00SPC200; CloudEngine 7800 V200R019C10SPC800.
CVE-2021-3939 1 Canonical 2 Accountsservice, Ubuntu Linux 2024-11-21 7.2 HIGH 7.8 HIGH
Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1.
CVE-2021-3682 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2024-11-21 6.0 MEDIUM 8.5 HIGH
A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host.

A CWE-763: Release of invalid pointer or reference vulnerability exists inIGSS Definition (Def.exe) V15.0.0.21140 and prior that could result in loss of data or remote code execution due to missing checks of user-supplied input data, when a malicious CGF file is imported to IGSS Definition.
CVE-2021-21401 1 Nanopb Project 1 Nanopb 2024-11-21 5.5 MEDIUM 7.1 HIGH
Nanopb is a small code-size Protocol Buffers implementation in ansi C. In Nanopb before versions 0.3.9.8 and 0.4.5, decoding a specifically formed message can cause invalid `free()` or `realloc()` calls if the message type contains an `oneof` field, and the `oneof` directly contains both a pointer field and a non-pointer field. If the message data first contains the non-pointer field and then the pointer field, the data of the non-pointer field is incorrectly treated as if it was a pointer value. Such message data rarely occurs in normal messages, but it is a concern when untrusted data is parsed. This has been fixed in versions 0.3.9.8 and 0.4.5. See referenced GitHub Security Advisory for more information including workarounds.
CVE-2020-9098 1 Huawei 2 Oceanstor 5310, Oceanstor 5310 Firmware 2024-11-21 7.8 HIGH 7.5 HIGH
