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. A malicious USB device may exploit the issue to cause memory corruption with controll... • https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=4ab3a086d10eeec1424f2e8a968827a6336203df • CWE-416: Use After Free •

CVE-2023-1195 – kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c
https://notcve.org/view.php?id=CVE-2023-1195
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 •
CVE-2023-1583
https://notcve.org/view.php?id=CVE-2023-1583
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 •
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') •

https://notcve.org/view.php?id=CVE-2023-1513
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 •
CVE-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. A use-after-free vulnerability was found in the ... • http://www.openwall.com/lists/oss-security/2023/04/11/3 • CWE-416: Use After Free •
