CVE-2021-3923 – kernel: stack information leak in infiniband RDMA
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 •
CVE-2023-1077 – Ubuntu Security Notice USN-6256-1
https://notcve.org/view.php?id=CVE-2023-1077
27 Mar 2023 — In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption. It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could pos... • https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=7c4a5b89a0b5a57a64b601775b296abf77a9fe97 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVE-2023-1079 – kernel: hid: Use After Free in asus_remove()
https://notcve.org/view.php?id=CVE-2023-1079
27 Mar 2023 — A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure.

CVE-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. It was discovered that the Traffic-Control Index implementation in the Linux kernel did not pro... • 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 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. It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions.

24 Mar 2023 — An issue was discovered in the Linux kernel before 5.8. lib/nlattr.c allows attackers to cause a denial of service (unbounded recursion) via a nested Netlink policy with a back reference. It was discovered that the netlink implementation in the Linux kernel did not properly validate policies when parsing attributes in some situations.

CVE-2023-28772 – kernel: lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow
https://notcve.org/view.php?id=CVE-2023-28772
23 Mar 2023 — An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow. A buffer overflow write flaw was identified in seq_buf_putmem_hex in lib/seq_buf.c in seq_buf in the Linux Kernel. This issue may allow a user with special debug privileges such as ftrace or root to cause an overflow in the destination buffer due to a missing sanity check. • https://github.com/Trinadh465/linux-4.1.15_CVE-2023-28772 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

CVE-2023-1249 – kernel: missing mmap_lock in file_files_note that could possibly lead to a use after free in the coredump code
https://notcve.org/view.php?id=CVE-2023-1249
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. The kernel tree of CentOS Stream 9 suffers from multiple use-after-free conditions that were already patched in upstream stable trees. • https://packetstorm.news/files/id/171912 • CWE-416: Use After Free •
