CVE-2026-46064

The CVE-2026-46064 issue affects the Linux kernel’s ibmasm path. The ibmasm_send_i2o_message() helper derives the memcpy_toio() byte count from user-controlled dot_command_header fields (command_size: u8, data_size: u16) via get_dot_command_size(), but does not validate against the actual allocat...

CVE-2026-46053

CVE-2026-46053 affects the Linux kernel RDS memory-registration cleanup. In net/rds, __rds_rdma_map() transfers ownership of sg/pages after get_mr(); if copying the cookie back to user space fails, resources could be freed more than once. The fix removes a duplicate unpin/free in the put_user() f...

CVE-2026-45990

CVE-2026-45990 concerns the Linux kernel slub allocator. The issue arises in krealloc/kvrealloc when forcing reallocation for new alignment or NUMA node even while shrinking, causing data loss during NUMA migration and a buffer overflow during shrinking due to using the old size for memcpy. The f...

CVE-2026-45958

The CVE-2026-45958 vulnerability affects the Linux kernel, specifically the drm/exynos vidi driver. In vidi_connection_ioctl(), the code dereferenced a user pointer directly (vidi->edid(user pointer)), enabling arbitrary kernel memory access from user space and potentially leading to privilege...

CVE-2026-45958

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi: fix to avoid directly dereferencing user pointer In vidiconnectionioctl, vidi-ediduser pointer is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user space, so instead o...

CVE-2026-45957

In the Linux kernel, the following vulnerability has been resolved: rcu: Fix rcureadunlock deadloop due to softirq Commit 5f5fa7ea89dc "rcu: Don't use negative nesting depth in rcureadunlock" removes the recursion-protection code from rcureadunlock. Therefore, we could invoke the deadloop in...

CVE-2026-45949 hwrng: core - use RCU and work_struct to fix race condition

In the Linux kernel, the following vulnerability has been resolved: hwrng: core - use RCU and workstruct to fix race condition Currently, hwrngfill is not cleared until the hwrngfillfn thread exits. Since hwrngunregister reads hwrngfill outside the rngmutex lock, a concurrent hwrngunregister may...

CVE-2026-45895 quota: fix livelock between quotactl and freeze_super

In the Linux kernel, the following vulnerability has been resolved: quota: fix livelock between quotactl and freezesuper When a filesystem is frozen, quotactlblock enters a retry loop waiting for the filesystem to thaw. It acquires sumount, checks the freeze state, drops sumount and uses...

CVE-2026-45852 RDMA/rxe: Fix double free in rxe_srq_from_init

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix double free in rxesrqfrominit In rxesrqfrominit, the queue pointer 'q' is assigned to 'srq-rq.queue' before copying the SRQ number to user space. If copytouser fails, the function calls rxequeuecleanup to free the...

CVE-2026-45852

Summary of CVE-2026-45852 (Linux kernel RDMA/rxe): A double-free vulnerability exists in the rxe_srq_from_init path of the RDMA subsystem. The queue pointer is temporarily assigned to srq->rq.queue before copy_to_user(), so if copy_to_user() fails, cleanup frees the same memory twice when the ...

UBUNTU-CVE-2026-45837

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free in arenavmclose on fork arenavmopen only bumps vml-mmapcount but never registers the child VMA in arena-vmalist. The vml-vma always points at the parent VMA, so after parent munmap the pointer dangles. If...

OpenSSH: OpenSSH: Privilege escalation via scp legacy protocol when not preserving file mode

A flaw was found in OpenSSH. When the scp command is used by a root user to download a file with the legacy protocol option -O and without preserving original file permissions -p, the downloaded file can be installed with elevated privileges setuid or setgid. This unexpected behavior could allow ...

CVE-2026-45837

The CVE-2026-45837 issue affects the Linux kernel BPF arena memory management during fork. The root cause is that arena_vm_open() bumps mmap_count but does not register the child VMA in arena->vma_list, leaving vml->vma to point to the parent VMA. After the parent unmaps, a use-after-free c...
