| CVE-2021-3491 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 7.8 High |
| The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b ("io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers") (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c ("io_uring: add IORING_OP_PROVIDE_BUFFERS") (v5.7-rc1). | ||||
| CVE-2021-3490 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 7.8 High |
| The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e ("bpf: Fix alu32 const subreg bound tracking on bitwise operations") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. The AND/OR issues were introduced by commit 3f50f132d840 ("bpf: Verifier, do explicit ALU32 bounds tracking") (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 ("bpf:Fix a verifier failure with xor") ( 5.10-rc1). | ||||
| CVE-2021-3489 | 3 Canonical, Linux, Redhat | 3 Ubuntu Linux, Linux Kernel, Enterprise Linux | 2024-11-21 | 7.8 High |
| The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee ("bpf, ringbuf: Deny reserve of buffers larger than ringbuf") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") (v5.8-rc1). | ||||
| CVE-2021-3483 | 3 Debian, Linux, Netapp | 19 Debian Linux, Linux Kernel, Cloud Backup and 16 more | 2024-11-21 | 7.8 High |
| A flaw was found in the Nosy driver in the Linux kernel. This issue allows a device to be inserted twice into a doubly-linked list, leading to a use-after-free when one of these devices is removed. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Versions before kernel 5.12-rc6 are affected | ||||
| CVE-2021-3444 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2024-11-21 | 7.8 High |
| The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and possibly out-of-bounds writes that could potentially lead to code execution. This issue was addressed in the upstream kernel in commit 9b00f1b78809 ("bpf: Fix truncation handling for mod32 dst reg wrt zero") and in Linux stable kernels 5.11.2, 5.10.19, and 5.4.101. | ||||
| CVE-2021-3428 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-11-21 | 5.5 Medium |
| A flaw was found in the Linux kernel. A denial of service problem is identified if an extent tree is corrupted in a crafted ext4 filesystem in fs/ext4/extents.c in ext4_es_cache_extent. Fabricating an integer overflow, A local attacker with a special user privilege may cause a system crash problem which can lead to an availability threat. | ||||
| CVE-2021-3411 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-11-21 | 6.7 Medium |
| 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. | ||||
| CVE-2021-3348 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-11-21 | 7.0 High |
| nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup, aka CID-b98e762e3d71. | ||||
| CVE-2021-3347 | 4 Debian, Fedoraproject, Linux and 1 more | 10 Debian Linux, Fedora, Linux Kernel and 7 more | 2024-11-21 | 7.8 High |

| CVE-2021-3178 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-11-21 | 6.5 Medium |
| fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this attack; see also the exports(5) no_subtree_check default behavior | ||||
| CVE-2021-3100 | 2 Amazon, Linux | 2 Log4jhotpatch, Linux Kernel | 2024-11-21 | 8.8 High |
| The Apache Log4j hotpatch package before log4j-cve-2021-44228-hotpatch-1.1-13 didn’t mimic the permissions of the JVM being patched, allowing it to escalate privileges. | ||||
| CVE-2021-39823 | 2 Adobe, Linux | 2 Svg-native-viewer, Linux Kernel | 2024-11-21 | 7.8 High |
| Adobe svg-native-viewer 8182d14dfad5d1e10f53ed830328d7d9a3cfa96d and earlier versions are affected by a heap buffer overflow vulnerability due to insecure handling of a malicious .svg file, potentially resulting in arbitrary code execution in the context of the current user.
