| CVE-2023-54030 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: io_uring/net: don't overflow multishot recv Don't allow overflowing multishot recv CQEs, it might get out of hand, hurt performance, and in the worst case scenario OOM the task. | ||||
| CVE-2023-54025 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: Do not configure WoWlan in shutdown hook if not enabled In case WoWlan was never configured during the operation of the system, the hw->wiphy->wowlan_config will be NULL. rsi_config_wowlan() checks whether wowlan_config is non-NULL and if it is not, then WARNs about it. The warning is valid, as during normal operation the rsi_config_wowlan() should only ever be called with non-NULL wowlan_config. In shutdown this rsi_config_wowlan() should only ever be called if WoWlan was configured before by the user. Add checks for non-NULL wowlan_config into the shutdown hook. While at it, check whether the wiphy is also non-NULL before accessing wowlan_config . Drop the single-use wowlan_config variable, just inline it into function call. | ||||

| In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race between balance and cancel/pause Syzbot reported a panic that looks like this: assertion failed: fs_info->exclusive_operation == BTRFS_EXCLOP_BALANCE_PAUSED, in fs/btrfs/ioctl.c:465 ------------[ cut here ]------------ kernel BUG at fs/btrfs/messages.c:259! RIP: 0010:btrfs_assertfail+0x2c/0x30 fs/btrfs/messages.c:259 Call Trace: <TASK> btrfs_exclop_balance fs/btrfs/ioctl.c:465 [inline] btrfs_ioctl_balance fs/btrfs/ioctl.c:3564 [inline] btrfs_ioctl+0x531e/0x5b30 fs/btrfs/ioctl.c:4632 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x197/0x210 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x39/0xb0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd The reproducer is running a balance and a cancel or pause in parallel. The way balance finishes is a bit wonky, if we were paused we need to save the balance_ctl in the fs_info, but clear it otherwise and cleanup. However we rely on the return values being specific errors, or having a cancel request or no pause request. If balance completes and returns 0, but we have a pause or cancel request we won't do the appropriate cleanup, and then the next time we try to start a balance we'll trip this ASSERT. The error handling is just wrong here, we always want to clean up, unless we got -ECANCELLED and we set the appropriate pause flag in the exclusive op. With this patch the reproducer ran for an hour without tripping, previously it would trip in less than a few minutes. | ||||
| CVE-2023-54022 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential memory leaks at error path for UMP open The allocation and initialization errors at alloc_midi_urbs() that is called at MIDI 2.0 / UMP device are supposed to be handled at the caller side by invoking free_midi_urbs(). However, free_midi_urbs() loops only for ep->num_urbs entries, and since ep->num_entries wasn't updated yet at the allocation / init error in alloc_midi_urbs(), this entry won't be released. The intention of free_midi_urbs() is to release the whole elements, so change the loop size to NUM_URBS to scan over all elements for fixing the missed releases. Also, the call of free_midi_urbs() is missing at snd_usb_midi_v2_open(). Although it'll be released later at reopen/close or disconnection, it's better to release immediately at the error path. | ||||
| CVE-2023-54020 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: sf-pdma: pdma_desc memory leak fix Commit b2cc5c465c2c ("dmaengine: sf-pdma: Add multithread support for a DMA channel") changed sf_pdma_prep_dma_memcpy() to unconditionally allocate a new sf_pdma_desc each time it is called. The driver previously recycled descs, by checking the in_use flag, only allocating additional descs if the existing one was in use. This logic was removed in commit b2cc5c465c2c ("dmaengine: sf-pdma: Add multithread support for a DMA channel"), but sf_pdma_free_desc() was not changed to handle the new behaviour. As a result, each time sf_pdma_prep_dma_memcpy() is called, the previous descriptor is leaked, over time leading to memory starvation: unreferenced object 0xffffffe008447300 (size 192): comm "irq/39-mchp_dsc", pid 343, jiffies 4294906910 (age 981.200s) hex dump (first 32 bytes): 00 00 00 ff 00 00 00 00 b8 c1 00 00 00 00 00 00 ................ 00 00 70 08 10 00 00 00 00 00 00 c0 00 00 00 00 ..p............. backtrace: [<00000000064a04f4>] kmemleak_alloc+0x1e/0x28 [<00000000018927a7>] kmem_cache_alloc+0x11e/0x178 [<000000002aea8d16>] sf_pdma_prep_dma_memcpy+0x40/0x112 Add the missing kfree() to sf_pdma_free_desc(), and remove the redundant in_use flag. | ||||

| In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: fix possible memory leak in ibmebus_bus_init() If device_register() returns error in ibmebus_bus_init(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked. As comment of device_add() says, it should call put_device() to drop the reference count that was set in device_initialize() when it fails, so the name can be freed in kobject_cleanup(). | ||||
| CVE-2023-54016 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix memory leak in rx_desc and tx_desc Currently when ath12k_dp_cc_desc_init() is called we allocate memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during descriptor cleanup rx_descs and tx_descs memory is not freed. This is cause of memory leak. These allocated memory should be freed in ath12k_dp_cc_cleanup. In ath12k_dp_cc_desc_init(), we can save base address of rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and tx_descs memory using their base address.

However, this priv might have been allocated by a different thread, and freeing it might lead to use-after-free bugs. Fix it by freeing the priv only in case it was allocated by the running thread. | ||||

| In the Linux kernel, the following vulnerability has been resolved: i2c: cadence: cdns_i2c_master_xfer(): Fix runtime PM leak on error path The cdns_i2c_master_xfer() function gets a runtime PM reference when the function is entered. This reference is released when the function is exited. There is currently one error path where the function exits directly, which leads to a leak of the runtime PM reference. Make sure that this error path also releases the runtime PM reference. | ||||

However, since these two reads are not atomically executed, there is a chance of a race condition as described above. To fix this race condition, read vmci_host_dev->context after checking the value of vmci_host_dev->ct_type so that vmci_host_poll() always reads an initialized context. | ||||
