|---|---|---|---|
| 2024-02-29 | CVE-2023-52477 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: usb: hub: Guard against accesses to uninitialized BOS descriptors Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h access fields inside udev->bos without checking if it was allocated and initialized. | 5.5 |
| 2024-02-29 | CVE-2023-52478 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: logitech-hidpp: Fix kernel crash on receiver USB disconnect hidpp_connect_event() has *four* time-of-check vs time-of-use (TOCTOU) races when it races with itself. hidpp_connect_event() primarily runs from a workqueue but it also runs on probe() and if a "device-connected" packet is received by the hw when the thread running hidpp_connect_event() from probe() is waiting on the hw, then a second thread running hidpp_connect_event() will be started from the workqueue. This opens the following races (note the below code is simplified): 1. | 4.7 |
| 2024-02-29 | CVE-2023-52480 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix race condition between session lookup and expire Thread A + Thread B ksmbd_session_lookup | smb2_sess_setup sess = xa_load | | | xa_erase(&conn->sessions, sess->id); | | ksmbd_session_destroy(sess) --> kfree(sess) | // UAF! | sess->last_active = jiffies | + This patch add rwsem to fix race condition between ksmbd_session_lookup and ksmbd_expire_session. | 7.0 |
| 2024-02-29 | CVE-2023-52483 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mctp: perform route lookups under a RCU read-side lock Our current route lookups (mctp_route_lookup and mctp_route_lookup_null) traverse the net's route list without the RCU read lock held. | 7.8 |
| 2024-02-26 | CVE-2024-26602 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: sched/membarrier: reduce the ability to hammer on sys_membarrier On some systems, sys_membarrier can be very expensive, causing overall slowdowns for everything. | 5.5 |
| 2024-02-26 | CVE-2024-26603 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Stop relying on userspace for info to fault in xsave buffer Before this change, the expected size of the user space buffer was taken from fx_sw->xstate_size. | 5.5 |
| 2024-02-26 | CVE-2024-26606 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: binder: signal epoll threads of self-work In (e)poll mode, threads often depend on I/O events to determine when data is ready for consumption. | 5.5 |
| 2024-02-26 | CVE-2023-52465 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: power: supply: Fix null pointer dereference in smb2_probe devm_kasprintf and devm_kzalloc return a pointer to dynamically allocated memory which can be NULL upon failure. | 5.5 |
| 2024-02-26 | CVE-2023-52467 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mfd: syscon: Fix null pointer dereference in of_syscon_register() kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. | 5.5 |
| 2024-02-26 | CVE-2023-52468 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: class: fix use-after-free in class_register() The lock_class_key is still registered and can be found in lock_keys_hash hlist after subsys_private is freed in error handler path.A task who iterate over the lock_keys_hash later may cause use-after-free.So fix that up and unregister the lock_class_key before kfree(cp). On our platform, a driver fails to kset_register because of creating duplicate filename '/class/xxx'.With Kasan enabled, it prints a invalid-access bug report. KASAN bug report: BUG: KASAN: invalid-access in lockdep_register_key+0x19c/0x1bc Write of size 8 at addr 15ffff808b8c0368 by task modprobe/252 Pointer tag: [15], memory tag: [fe] CPU: 7 PID: 252 Comm: modprobe Tainted: G W 6.6.0-mainline-maybe-dirty #1 Call trace: dump_backtrace+0x1b0/0x1e4 show_stack+0x2c/0x40 dump_stack_lvl+0xac/0xe0 print_report+0x18c/0x4d8 kasan_report+0xe8/0x148 __hwasan_store8_noabort+0x88/0x98 lockdep_register_key+0x19c/0x1bc class_register+0x94/0x1ec init_module+0xbc/0xf48 [rfkill] do_one_initcall+0x17c/0x72c do_init_module+0x19c/0x3f8 ...

It's worth noting that this only can happen if lockdep is enabled, which is not true for normal system. | 7.8 |
