27 Mar 2023 — A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service. • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html • CWE-125: Out-of-bounds Read •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28866 – kernel: Bluetooth: HCI: global out-of-bounds access in net/bluetooth/hci_sync.c
https://notcve.org/view.php?id=CVE-2023-28866
27 Mar 2023 — In the Linux kernel through 6.2.8, net/bluetooth/hci_sync.c allows out-of-bounds access because amp_init1[] and amp_init2[] are supposed to have an intentionally invalid element, but do not. An out-of-bounds (OOB) memory access flaw was found in net/bluetooth/hci_sync.c due to a missing exit patch while in loop in amp_init1[] and amp_init2[]. This issue could allow an attacker to leak internal kernel information. • https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=95084403f8c070ccf5d7cbe72352519c1798a40a • CWE-125: Out-of-bounds Read •

27 Mar 2023 — A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks.

https://notcve.org/view.php?id=CVE-2021-3923
27 Mar 2023 — A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms. • https://bugzilla.redhat.com/show_bug.cgi?id=2019643 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

24 Mar 2023 — A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an invalid pointer request. • https://github.com/torvalds/linux/commit/153695d36ead0ccc4d0256953c751cabf673e621 • CWE-416: Use After Free •

24 Mar 2023 — A NULL pointer dereference was found in io_file_bitmap_get in io_uring/filetable.c in the io_uring sub-component in the Linux Kernel. When fixed files are unregistered, some context information (file_alloc_{start,end} and alloc_hint) is not cleared. A subsequent request that has auto index selection enabled via IORING_FILE_INDEX_ALLOC can cause a NULL pointer dereference. An unprivileged user can use the flaw to cause a system crash. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=02a4d923e4400a36d340ea12d8058f69ebf3a383 • CWE-476: NULL Pointer Dereference •

23 Mar 2023 — A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak. • https://bugzilla.redhat.com/show_bug.cgi?id=2179892 • CWE-665: Improper Initialization •
CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 0CVE-2023-1281 – UAF in Linux kernel's tcindex (traffic control index filter) implementation
https://notcve.org/view.php?id=CVE-2023-1281
22 Mar 2023 — Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2.

21 Mar 2023 — A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected. • http://packetstormsecurity.com/files/171912/CentOS-Stream-9-Missing-Kernel-Security-Fix.html • CWE-416: Use After Free •
