| In the Linux kernel, the following vulnerability has been resolved: cxl/acpi: Fix a use-after-free in cxl_parse_cfmws() KASAN and KFENCE detected an user-after-free in the CXL driver. This happens in the cxl_decoder_add() fail path. KASAN prints the following error: BUG: KASAN: slab-use-after-free in cxl_parse_cfmws (drivers/cxl/acpi.c:299) This happens in cxl_parse_cfmws(), where put_device() is called, releasing cxld, which is accessed later. Use the local variables in the dev_err() instead of pointing to the released memory. Since the dev_err() is printing a resource, change the open coded print format to use the %pr format specifier. | |||||

| In the Linux kernel, the following vulnerability has been resolved: ipv6: Add lwtunnel encap size of all siblings in nexthop calculation In function rt6_nlmsg_size(), the length of nexthop is calculated by multipling the nexthop length of fib6_info and the number of siblings. However if the fib6_info has no lwtunnel but the siblings have lwtunnels, the nexthop length is less than it should be, and it will trigger a warning in inet6_rt_notify() as follows: WARNING: CPU: 0 PID: 6082 at net/ipv6/route.c:6180 inet6_rt_notify+0x120/0x130 ......

| In the Linux kernel, the following vulnerability has been resolved: iw_cxgb4: Fix potential NULL dereference in c4iw_fill_res_cm_id_entry() This condition needs to match the previous "if (epcp->state == LISTEN) {" exactly to avoid a NULL dereference of either "listen_ep" or "ep". The problem is that "epcp" has been re-assigned so just testing "if (epcp->state == LISTEN) {" a second time is not sufficient. | |||||

| CVE-2023-53472 | 1 Linux | 1 Linux Kernel | 2026-06-17 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: pwm: lpc32xx: Remove handling of PWM channels Because LPC32xx PWM controllers have only a single output which is registered as the only PWM device/channel per controller, it is known in advance that pwm->hwpwm value is always 0. On basis of this fact simplify the code by removing operations with pwm->hwpwm, there is no controls which require channel number as input. Even though I wasn't aware at the time when I forward ported that patch, this fixes a null pointer dereference as lpc32xx->chip.pwms is NULL before devm_pwmchip_add() is called. | |||||

| CVE-2023-53461 | 1 Linux | 1 Linux Kernel | 2026-06-17 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: io_uring: wait interruptibly for request completions on exit WHen the ring exits, cleanup is done and the final cancelation and waiting on completions is done by io_ring_exit_work. That function is invoked by kworker, which doesn't take any signals. Because of that, it doesn't really matter if we wait for completions in TASK_INTERRUPTIBLE or TASK_UNINTERRUPTIBLE state. However, it does matter to the hung task detection checker! Normally we expect cancelations and completions to happen rather quickly. Some test cases, however, will exit the ring and park the owning task stopped (eg via SIGSTOP). If the owning task needs to run task_work to complete requests, then io_ring_exit_work won't make any progress until the task is runnable again. Hence io_ring_exit_work can trigger the hung task detection, which is particularly problematic if panic-on-hung-task is enabled. As the ring exit doesn't take signals to begin with, have it wait interruptibly rather than uninterruptibly. io_uring has a separate stuck-exit warning that triggers independently anyway, so we're not really missing anything by making this switch. | |||||

| In the Linux kernel, the following vulnerability has been resolved: media: cx23885: Fix a null-ptr-deref bug in buffer_prepare() and buffer_finish() When the driver calls cx23885_risc_buffer() to prepare the buffer, the function call dma_alloc_coherent may fail, resulting in a empty buffer risc->cpu. Later when we free the buffer or access the buffer, null ptr deref is triggered. This bug is similar to the following one: https://git.linuxtv.org/media_stage.git/commit/?id=2b064d91440b33fba5b452f2d1b31f13ae911d71. We believe the bug can be also dynamically triggered from user side. Similarly, we fix this by checking the return value of cx23885_risc_buffer() and the value of risc->cpu before buffer free. | |||||

| In the Linux kernel, the following vulnerability has been resolved: scsi: qla4xxx: Add length check when parsing nlattrs There are three places that qla4xxx parses nlattrs: - qla4xxx_set_chap_entry() - qla4xxx_iface_set_param() - qla4xxx_sysfs_ddb_set_param() and each of them directly converts the nlattr to specific pointer of structure without length checking. This could be dangerous as those attributes are not validated and a malformed nlattr (e.g., length 0) could result in an OOB read that leaks heap dirty data. Add the nla_len check before accessing the nlattr data and return EINVAL if the length check fails. | |||||

Currently, vc4 is not dealing with the deadlock properly, producing the following output when PROVE_LOCKING is enabled: [ 825.612809] ------------[ cut here ]------------ [ 825.612852] WARNING: CPU: 1 PID: 116 at drivers/gpu/drm/drm_modeset_lock.c:276 drm_modeset_drop_locks+0x60/0x68 [drm] [ 825.613458] Modules linked in: 8021q mrp garp stp llc raspberrypi_cpufreq brcmfmac brcmutil crct10dif_ce hci_uart cfg80211 btqca btbcm bluetooth vc4 raspberrypi_hwmon snd_soc_hdmi_codec cec clk_raspberrypi ecdh_generic drm_display_helper ecc rfkill drm_dma_helper drm_kms_helper pwm_bcm2835 bcm2835_thermal bcm2835_rng rng_core i2c_bcm2835 drm fuse ip_tables x_tables ipv6 [ 825.613735] CPU: 1 PID: 116 Comm: kworker/1:2 Tainted: G W 6.1.0-rc6-01399-g941aae326315 #3 [ 825.613759] Hardware name: Raspberry Pi 3 Model B Rev 1.2 (DT) [ 825.613777] Workqueue: events output_poll_execute [drm_kms_helper] [ 825.614038] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 825.614063] pc : drm_modeset_drop_locks+0x60/0x68 [drm] [ 825.614603] lr : drm_helper_probe_detect+0x120/0x1b4 [drm_kms_helper] [ 825.614829] sp : ffff800008313bf0 [ 825.614844] x29: ffff800008313bf0 x28: ffffcd7778b8b000 x27: 0000000000000000 [ 825.614883] x26: 0000000000000001 x25: 0000000000000001 x24: ffff677cc35c2758 [ 825.614920] x23: ffffcd7707d01430 x22: ffffcd7707c3edc7 x21: 0000000000000001 [ 825.614958] x20: 0000000000000000 x19: ffff800008313c10 x18: 000000000000b6d3 [ 825.614995] x17: ffffcd777835e214 x16: ffffcd7777cef870 x15: fffff81000000000 [ 825.615033] x14: 0000000000000000 x13: 0000000000000099 x12: 0000000000000002 [ 825.615070] x11: 72917988020af800 x10: 72917988020af800 x9 : 72917988020af800 [ 825.615108] x8 : ffff677cc665e0a8 x7 : d00a8c180000110c x6 : ffffcd77774c0054 [ 825.615145] x5 : 0000000000000000 x4 : 0000000000000001 x3 : 0000000000000000 [ 825.615181] x2 : ffff677cc55e1880 x1 : ffffcd7777cef8ec x0 : ffff800008313c10 [ 825.615219] Call trace: [ 825.615232] drm_modeset_drop_locks+0x60/0x68 [drm] [ 825.615773] drm_helper_probe_detect+0x120/0x1b4 [drm_kms_helper] [ 825.616003] output_poll_execute+0xe4/0x224 [drm_kms_helper] [ 825.616233] process_one_work+0x2b4/0x618 [ 825.616264] worker_thread+0x24c/0x464 [ 825.616288] kthread+0xec/0x110 [ 825.616310] ret_from_fork+0x10/0x20 [ 825.616335] irq event stamp: 7634 [ 825.616349] hardirqs last enabled at (7633): [<ffffcd777831ee90>] _raw_spin_unlock_irq+0x3c/0x78 [ 825.616384] hardirqs last disabled at (7634): [<ffffcd7778315a78>] __schedule+0x134/0x9f0 [ 825.616411] softirqs last enabled at (7630): [<ffffcd7707aacea0>] local_bh_enable+0x4/0x30 [ipv6] [ 825.617019] softirqs last disabled at (7618): [<ffffcd7707aace70>] local_bh_disable+0x4/0x30 [ipv6] [ 825.617586] ---[ end trace 0000000000000000 ]--- Therefore, deal with the deadlock as suggested by [1], using the function drm_modeset_backoff().
