A flaw was found in the MariaDB Server, where it contains a use-after-free in the component, Itemfuncin::cleanup. This issue is exploited via specially crafted SQL statements, affecting availability...

mariadb: server crash in Item_func_in::cleanup/Item::cleanup_processor

MariaDB v10.2 to v10.7 was discovered to contain a segmentation fault via the component Itemfuncin::cleanup/Item::cleanupprocessor...

kernel: net/sched: cls_fw component can be exploited as result of failure in tcf_change_indev function

A use-after-free vulnerability was found in fwsetparms in net/sched/clsfw.c in network scheduler sub-component in the Linux Kernel. This issue occurs due to a missing sanity check during cleanup at the time of failure, leading to a misleading reference. This may allow a local attacker to gain loc...

kernel: xhci: Remove device endpoints from bandwidth list when freeing the device

A null pointer/list corruption flaw was found in the Linux kernel USB xHCI host controller code. When the xHCI host is dying or being removed, some device endpoints may remain on the software bandwidth list. Later cleanup deletes entries that were already freed, corrupting the list and crashing t...

kernel: cifs: Fix memory leak on the deferred close

In the Linux kernel, the following vulnerability has been resolved: cifs: Fix memory leak on the deferred close xfstests on smb21 report kmemleak as below: unreferenced object 0xffff8881767d6200 size 64: comm "xfsio", pid 1284, jiffies 4294777434 age 20.789s hex dump first 32 bytes: 80 5a d0 11 8...

kernel: Linux kernel: Denial of Service due to improper io_uring/af_unix file cleanup

A flaw was found in the Linux kernel's iouring/afunix component. A local user could exploit improper handling of registered files during garbage collection. This vulnerability can lead to a memory leak, potentially causing a denial of service DoS on the system...

kernel: RDMA/rxe: Fix BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanup

A flaw was found in the rdmarxe module in the Linux kernel. A NULL pointer dereference can be triggered when an error occurs due to an improper check, resulting in a denial of service...

kernel: watch_queue: Fix NULL dereference in error cleanup

In the Linux kernel, the following vulnerability has been resolved: watchqueue: Fix NULL dereference in error cleanup In watchqueuesetsize, the error cleanup code doesn't take account of the fact that freepage can't handle a NULL pointer when trying to free up buffer pages that did get allocated...

kernel: mptcp: use the workqueue to destroy unaccepted sockets

In the Linux kernel, the following vulnerability has been resolved: mptcp: use the workqueue to destroy unaccepted sockets Christoph reported a UaF at token lookup time after having refactored the passive socket initialization part: BUG: KASAN: use-after-free in tokenbucketbusy+0x253/0x260 Read o...

kernel: net/mlx5: Fix steering rules cleanup

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix steering rules cleanup vport's mc, uc and multicast rules are not deleted in teardown path when EEH happens. Since the vport's promisc settingsuc, mc and all in firmware are reset after EEH, mlx5 driver will try to...

kernel: Linux kernel: Denial of Service in io_uring due to hung task detection

A flaw was identified in the Linux kernel’s iouring subsystem related to how request completions are handled when an iouring instance exits. During cleanup, the function ioringexitwork was waiting in an uninterruptible state for request completions. Under certain test and signal conditions e.g.,...

kernel: s390/vfio-ap: fix memory leak in vfio_ap device driver

In the s390 VFIO-AP driver, memory allocated for the vfiomatrixdev structure is never released during device cleanup. The release callback incorrectly uses devgetdrvdata to locate the object, but since it was never stored there, the function returns NULL and kfree silently accepts it. The correct...

kernel: vfio: Fix NULL pointer dereference caused by uninitialized group->iommufd

A NULL pointer dereference was found in the VFIO subsystem. When a VFIO group operation fails before group-iommufd is initialized, the cleanup path calls iommufdctxput with a NULL pointer, causing a kernel crash...

kernel: wifi: mt76: dma: fix memory leak running mt76_dma_tx_cleanup

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: dma: fix memory leak running mt76dmatxcleanup Fix device unregister memory leak and alway cleanup all configured rx queues in mt76dmatxcleanup routine...

kernel: driver core: fix resource leak in device_add()

A reference leak was found in the Linux kernel's driver core device registration logic. When kobjectadd fails partway through deviceadd, the error cleanup attempts to free resources but fails because kobjectadd has already cleared the device's parent pointer. This prevents cleanupgluedir from...

kernel: USB: gadget: Fix use-after-free during usb config switch

A use-after-free vulnerability was found in the Linux kernel's USB gadget subsystem. When switching USB configuration from RNDIS to another configuration, if the hardware's pullup callback fails either unsupported or hardware fault, the error handling path triggers rndisclose on already-freed...

kernel: dm stats: check for and propagate alloc_percpu failure

In the Linux kernel, the following vulnerability has been resolved: dm stats: check for and propagate allocpercpu failure Check allocprecpu's return value and return an error from dmstatsinit if it fails. Update allocdev to fail if dmstatsinit does. Otherwise, a NULL pointer dereference will occu...

kernel: net/mlx5e: Fix cleanup null-ptr deref on encap lock

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix cleanup null-ptr deref on encap lock During module is unloaded while a peer tc flow is still offloaded, first the peer uplink rep profile is changed to a nic profile, and so neigh encap lock is destroyed. Next duri...
