Vulnerabilities

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ASoC: amd/sdw_utils: avoid NULL deref when devm_kasprintf() fails<br /> <br /> devm_kasprintf() may return NULL on memory allocation failure,<br /> but the debug message prints cpus-&gt;dai_name before checking it.<br /> Move the dev_dbg() call after the NULL check to prevent potential<br /> NULL pointer dereference.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> sched/deadline: Stop dl_server before CPU goes offline<br /> <br /> IBM CI tool reported kernel warning[1] when running a CPU removal<br /> operation through drmgr[2]. i.e "drmgr -c cpu -r -q 1"<br /> <br /> WARNING: CPU: 0 PID: 0 at kernel/sched/cpudeadline.c:219 cpudl_set+0x58/0x170<br /> NIP [c0000000002b6ed8] cpudl_set+0x58/0x170<br /> LR [c0000000002b7cb8] dl_server_timer+0x168/0x2a0<br /> Call Trace:<br /> [c000000002c2f8c0] init_stack+0x78c0/0x8000 (unreliable)<br /> [c0000000002b7cb8] dl_server_timer+0x168/0x2a0<br /> [c00000000034df84] __hrtimer_run_queues+0x1a4/0x390<br /> [c00000000034f624] hrtimer_interrupt+0x124/0x300<br /> [c00000000002a230] timer_interrupt+0x140/0x320<br /> <br /> Git bisects to: commit 4ae8d9aa9f9d ("sched/deadline: Fix dl_server getting stuck")<br /> <br /> This happens since:<br /> - dl_server hrtimer gets enqueued close to cpu offline, when<br /> kthread_park enqueues a fair task.<br /> - CPU goes offline and drmgr removes it from cpu_present_mask.<br /> - hrtimer fires and warning is hit.<br /> <br /> Fix it by stopping the dl_server before CPU is marked dead.<br /> <br /> [1]: https://lore.kernel.org/all/8218e149-7718-4432-9312-f97297c352b9@linux.ibm.com/<br /> [2]: https://github.com/ibm-power-utilities/powerpc-utils/tree/next/src/drmgr<br /> <br /> [sshegde: wrote the changelog and tested it]

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: nxp: imx8-isi: m2m: Fix streaming cleanup on release<br /> <br /> If streamon/streamoff calls are imbalanced, such as when exiting an<br /> application with Ctrl+C when streaming, the m2m usage_count will never<br /> reach zero and the ISI channel won&amp;#39;t be freed.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe/guc: Check GuC running state before deregistering exec queue<br /> <br /> In normal operation, a registered exec queue is disabled and<br /> deregistered through the GuC, and freed only after the GuC confirms<br /> completion. However, if the driver is forced to unbind while the exec<br /> queue is still running, the user may call exec_destroy() after the GuC<br /> has already been stopped and CT communication disabled.<br /> <br /> In this case, the driver cannot receive a response from the GuC,<br /> preventing proper cleanup of exec queue resources. Fix this by directly<br /> releasing the resources when GuC is not running.<br /> <br /> Here is the failure dmesg log:<br /> "<br /> [ 468.089581] ---[ end trace 0000000000000000 ]---<br /> [ 468.089608] pci 0000:03:00.0: [drm] *ERROR* GT0: GUC ID manager unclean (1/65535)<br /> [ 468.090558] pci 0000:03:00.0: [drm] GT0: total 65535<br /> [ 468.090562] pci 0000:03:00.0: [drm] GT0: used 1<br /> [ 468.090564] pci 0000:03:00.0: [drm] GT0: range 1..1 (1)<br /> [ 468.092716] ------------[ cut here ]------------<br /> [ 468.092719] WARNING: CPU: 14 PID: 4775 at drivers/gpu/drm/xe/xe_ttm_vram_mgr.c:298 ttm_vram_mgr_fini+0xf8/0x130 [xe]<br /> "<br /> <br /> v2: use xe_uc_fw_is_running() instead of xe_guc_ct_enabled().<br /> As CT may go down and come back during VF migration.<br /> <br /> (cherry picked from commit 9b42321a02c50a12b2beb6ae9469606257fbecea)
