CVE-2025-22060

CVE-2025-22060 concerns the Linux kernel mvpp2 parser TCAM/SRAM memory. The issue arises when concurrent accesses to the indirect TCAM/SRAM tables via an index register are not atomic, enabling TOCTOU-like corruption when mvpp2_set_rx_mode() runs on multiple CPUs. In the described scenario, this ...

CVE-2025-22058

CVE-2025-22058 affects the Linux kernel UDP memory accounting. When INT_MAX was used for SO_RCVBUF, an overflow in udp_rmem_release() could wrap the total UDP memory, causing memory accounting to double after socket close and potentially leading to packet drops once rmem_alloc exceeded net.ipv4.u...

CVE-2025-22055

CVE-2025-22055 affects the Linux kernel: a vulnerability in geneve_opt length handling (5-bit length per option) can let an attacker craft a 128-byte option to cause a heap out-of-bounds read. The issue originates from Netlink policy length guarantees not enforcing the 128-byte bound. The provide...

In the Linux kernel, the following vulnerability has been resolved: arcnet: Add NULL check in com20020pciprobe devmkasprintf returns NULL when memory allocation fails. Currently, com20020pciprobe does not check for this case, which results in a NULL pointer dereference. Add NULL check after...

CVE-2025-22053 net: ibmveth: make veth_pool_store stop hanging

In the Linux kernel, the following vulnerability has been resolved: net: ibmveth: make vethpoolstore stop hanging v2: - Created a single error handling unlock and exit in vethpoolstore - Greatly expanded commit message with previous explanatory-only text Summary: Use rtnlmutex to synchronize...

CVE-2025-22053

The CVE-2025-22053 issue affects the Linux kernel’s ibmveth driver, specifically the veth_pool_store path. The root cause is a race/ synchronization gap allowing two or more threads to enter veth_pool_store concurrently (via /sys/devices/vio/30000002/pool*/), which could lead to a hang. The provi...

CVE-2025-22051

CVE-2025-22051 affects the Linux kernel staging gpib driver. The issue arises when an Agilent USB dongle is disconnected, causing a NULL pointer Oops on subsequent driver calls because bus_interface is set to NULL on disconnect. The root cause is that usb_dev was being assigned from the bus_inter...

CVE-2025-22048

The CVE-2025-22048 entry concerns LoongArch support in the Linux kernel where BPF return-value handling was fixed. The root cause was that after a commit that sign-extended the a5 return register to a0, the subsequent propagation from a0 back to a5 occurred for all function calls, which was incor...

CVE-2025-22048 LoongArch: BPF: Don't override subprog's return value

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Don't override subprog's return value The verifier test calls: div by 0 in subprog triggers a panic at the ld.bu instruction. The ld.bu insn is trying to load byte from memory address returned by the subprog. The...
