| CVE-2026-111603 | 1 Playeduos | 1 Playedu | 2026-10-23 | 4.3 Medium |
| PlayEdu through 2.3 contains a missing authorization vulnerability in the CourseController that allows authenticated students to access department-restricted courses by omitting the department visibility check. Attackers can enumerate sequential course and attachment IDs via the course details and attachment download endpoints to obtain course structure and attachment files from other departments. | ||||

| In the Linux kernel, the following vulnerability has been resolved: nvme-multipath: set BLK_FEAT_ZONED only after the zone info is known The namespace head is marked zoned at allocation time based only on the command set identifier. If the zone info query reports a zero zone size, the path namespace is registered without zoned limits while the head still advertises the zoned capability with a zone size of zero, and reporting zones or writing to the head then shifts by ilog2(0). Drop the zoned feature from the head allocation and let the head limits refresh stack it in from the path namespace instead. | ||||

| In the Linux kernel, the following vulnerability has been resolved: tpm: fix off-by-four bounds check in tpm2_get_random() When the response carries the TPM2_ST_SESSIONS tag, tpm2_get_random() skips the 4-byte parameter size field before locating the random data, but the bounds check still validates the response length against TPM_HEADER_SIZE. A truncated response can pass the check and make memcpy() read up to 4 bytes past the response end, so stale buffer contents end up in the caller's random bytes. Fix this by checking the response length against 'offset', which already includes the skipped parameter size field. | ||||

| CVE-2026-99004 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Size page table preallocation by device address Commit 0a8224058a58 ("drm/imagination: Fix page count for page table for map() interface") passed the device address to pvr_mmu_op_context_create(), but the preallocation is still sized from device_addr + sgt_offset with an exclusive end. The offset into the object's pages has no place in a device-virtual range, and the exclusive end allocates one table too many when the range ends on a table boundary. Count the tables from device_addr and the inclusive end of the range. The new calculation does not take page table indices into account. This fixes another issue with the previous implementation, where the difference between start and end indices could underflow when a mapping crossed a page table boundary. This would lead to the driver preallocating a huge number of MMU pages, exhausting system memory and triggering an out of memory panic.

| CVE-2026-99005 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Unmask interrupts only when ACTIVE is true There is a small race window between intel_rps_boost() reading a stale ACTIVE state and queuing rps->work, where ACTIVE may be changed via asynchronous calls triggered by wakeref drop. This means that rps_work() could be triggered after the GT has been parked, so unmasking RPS PM interrupts would happen without holding PM wakelock. This sequence of events may be observed during live_rc6_ctx_wa() selftest: 1) live_rc6_ctx_wa() -> intel_engine_pm_put() -> wakeref_put() ASYNC1) wakeref_put() callback -> __engine_park() -> intel_gt_pm_put_async() -> intel_gt_pm_put_async_untracked() -> intel_wakeref_put_async() ASYNC2) wakeref_put_async() callback -> __gt_park() -> intel_rps_park() -> intel_rps_clear_active() [clear ACTIVE] WITH INTERRUPTS: -> rps_disable_interrupts() -> cancel_work_sync(rps->work) -> rps_reset_interrupts() [rps->pm_iir = 0] WITHOUT INTERRUPTS (TIMER mode): -> rps_stop_timer() -> cancel_work_sync(rps->work) 2) live_rc6_ctx_wa() -> intel_gt_wait_for_idle() -> intel_gt_retire_requests_timeout() -> dma_fence_wait_timeout() -> ops->wait() [i915_fence_wait()] -> i915_request_wait_timeout() -> intel_rps_boost() -> intel_rps_is_active() [check ACTIVE] [OPEN RACE WINDOW] -> queue_work(rps->work) -> retire_requests() -> i915_request_retire() -> intel_rps_dec_waiters() [from 1 to 0] If ASYNC1 and ASYNC2 would execute during [OPEN RACE WINDOW], then: 3) rps_work() executes from the workqueue and may satisfy "(!pm_iir && !client_boost)" test (in TIMER mode rps->pm_iir is zeroed by an earlier rps_work() call or never gets a new value after previous intel_rps_unpark() event), so it jumps to "out" label, bypassing intel_rps_is_active() guard and executes gen6_gt_pm_unmask_irq(); 4) GT is parked and runtime PM wakelock is dropped, so only a raw reference in __gt_park() -> intel_display_power_put_async() remains for 100ms, then the MMIO write in gen6_gt_pm_unmask_irq() detects missing wakelock via assert_rpm_wakelock_held() and emits "RPM wakelock ref not held during HW access" tainting kernel. Commit 3e7abf814193 ("drm/i915: Extract GT render power state management") dropped the "if (rps->interrupts_enabled)" guard that gen6_pm_rps_work() had around this unmask in i915_irq.c. INTEL_RPS_ACTIVE brackets the same window, since it is set in intel_rps_unpark() before rps_enable_interrupts() and rps_start_timer() and cleared in intel_rps_park() before rps_stop_timer() and rps_disable_interrupts(). Skip unmasking when RPS is no longer active (reaching unmask operation is independent of INTERRUPT mode). This does not prevent RPS operation from resuming on the next unpark. In interrupt mode, intel_rps_unpark() calls rps_enable_interrupts(), which enables and unmasks the PM interrupts. In timer mode, it calls rps_start_timer(), restarting periodic engine-busyness evaluation. The timer generates software RPS events and queues rps_work() directly, independently of PM interrupt delivery. Neither mode requires the late worker to unmask interrupts while the GT is parked (cherry picked from commit ca4a6deadad15b91ee083afe445fa6bdbfb68206) | ||||
| CVE-2026-99006 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Prevent overstepping exec array boundary It is possible for eb_relocate_parse_slow() to call kvfree() on entries outside the original exec array during following scenario inside eb_relocate_parse_slow(): 1) eb_copy_relocations() allocates as many as eb->buffer_count copies for exec entries; 2) eb_parse() appends up to two VMAs, right after incrementing eb->buffer_count; 3) cleanup under "out" label uses this incremented buffer_count to release relocation pointers from exec array via kvfree(), not from VMA array. To amend this problem, ensure that relocation cleanup uses the original exec object count, excluding the VMAs appended by the command parser.

| CVE-2026-99008 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: Fix NULL tty_dev dereference in rfcomm_dev_shutdown syzbot hit a NULL pointer dereference in rfcomm_dev_shutdown() when an RFCOMM tty is closed. rfcomm_dev_add() puts the new device on rfcomm_dev_list first and only then registers the tty device and saves it in dev->tty_dev. If that registration fails, dev->tty_dev is never set at all. The device can be looked up in the meantime, so an open() of /dev/rfcommN gets through rfcomm_tty_install() and attaches to it. When that tty is closed again, rfcomm_dev_shutdown() uses dev->tty_dev without checking it: Oops: general protection fault, probably for non-canonical address KASAN: null-ptr-deref in range [0x0000000000000040-0x0000000000000047] RIP: 0010:rfcomm_dev_shutdown+0x48/0xb0 net/bluetooth/rfcomm/tty.c:131 Call Trace: tty_port_shutdown+0x1bf/0x220 drivers/tty/tty_port.c:372 tty_port_close+0x4e/0x150 drivers/tty/tty_port.c:705 tty_release+0x359/0x1670 drivers/tty/tty_io.c:1718 __fput+0x418/0xa50 fs/file_table.c:512 rfcomm_dev_destruct() already copes with a NULL dev->tty_dev. Add the same check to rfcomm_dev_shutdown(), so the tty device is only moved when it was actually registered. | ||||
