AZL-101243 CVE-2026-89802 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/uvmm: fix NULL deref unwinding an OPMAPSPARSE op Each bindjobop is zeroed by kzallocobj in bindjobopfromuop, and the OPMAPSPARSE case in nouveauuvmmbindjobsubmit only creates a region, so op-ops stays NULL for a...

CVE-2026-90042

CVE-2026-90042 affects the Linux kernel's Ceph filesystem client . The root cause is that the messenger client uses kvmalloc() to allocate message buffers, which can place them in the vmalloc() region when physical memory fragmentation prevents a sufficiently large kmalloc(). The fscrypt subsyste...

EUVD-2026-80650

In the Linux kernel, the following vulnerability has been resolved: ceph: properly decrypt filenames in vmalloc buffers The fscrypt subsystem uses the scatterlist crypto API, inheriting its requirement that any buffers are in the linear mapping region. However, the messenger client uses kvmalloc ...

CVE-2026-90042 ceph: properly decrypt filenames in vmalloc() buffers

In the Linux kernel, the following vulnerability has been resolved: ceph: properly decrypt filenames in vmalloc buffers The fscrypt subsystem uses the scatterlist crypto API, inheriting its requirement that any buffers are in the linear mapping region. However, the messenger client uses kvmalloc ...

CVE-2026-90012 spi: Fix DMA mapping ownership on partial map failure

In the Linux kernel, the following vulnerability has been resolved: spi: Fix DMA mapping ownership on partial map failure If RX mapping fails after TX mapping succeeds, spimapmsg unmaps TX but leaves txsgmapped set. If TX mapping fails on a later transfer, mappings created for earlier transfers...

CVE-2026-90012

CVE-2026-90012 is a Linux kernel SPI bug in DMA mapping ownership on partial map failure. When RX mapping fails after TX mapping succeeds, __spi_map_msg() unmaps TX but leaves tx_sg_mapped set, and cur_{tx,rx}_dma_dev are not yet updated. The subsequent spi_unmap_msg() can then double-free a TX m...

EUVD-2026-80598

In the Linux kernel, the following vulnerability has been resolved: ceph: lock mutex in cephmdscheckaccess MDS session OPEN handling replaces mdsc-scapauths under mdsc-mutex, freeing the previous array and its strings. cephmdscheckaccess traverses this array without holding the mutex. A concurren...

CVE-2026-89978 accel/amdxdna: return early from a zero-length flush

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: return early from a zero-length flush SYNCBO does not constrain its size, so a request for zero bytes reaches drmclflushvirtrange, which ends with an unconditional clflushoptend - 1. For an empty range that is the...

CVE-2026-89978

CVE-2026-89978 affects the Linux kernel accel/amdxdna driver (AMD NPU). The SYNC_BO ioctl does not validate that the requested size is non-zero, so a zero-byte request reaches drm_clflush_virt_range(), which unconditionally calls clflushopt(end - 1). For an empty range this dereferences the guard...

CVE-2026-89912

CVE-2026-89912 affects the Linux kernel in the KVM arm64 vgic-its subsystem. When a guest issues MAPC with V=0 , the ite->collection pointer is nulled while the ITE remains on the device's ITT list. The function vgic_its_save_ite() then dereferences this NULL pointer unconditionally when the V...

CVE-2026-89912 KVM: arm64: vgic-its: Don't dereference a NULL collection on ITT save

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Don't dereference a NULL collection on ITT save MAPC with V=0 drops ite-collection but leaves the ITE on the device's ITT list, and vgicitssaveite dereferences it unconditionally. A guest that issues MAPD,...

CVE-2026-89851

A bug in the Linux kernel scsi: qla2xxx driver (QLogic SCSI) affected the FCE trace enable write handler in debugfs (qla2x00_dfs_fce_write()). The function called kstrtoul() with a NULL result pointer , so a successful parse would dereference NULL and trigger a kernel oops . Additionally, the int...
