CVE-2025-38483

CVE-2025-38483 concerns the Linux kernel’s comedi das16m1 IRQ validation. The test for valid IRQs uses a bitmask check on (1 <options[1]), but it->options[i] is an unchecked int from userspace, allowing the shift amount to be negative or out of bounds. The fix adds a bounds check on it->...

CVE-2025-38477

The CVE-2025-38477 entry concerns a race in the Linux kernel’s net/sched qfq code. A concurrent modification of agg in qfq_change_agg (invoked during qfq_enqueue) could lead to a NULL dereference in qfq_dump_class and a use-after-free in qfq_delete_class. The fix moves qfq_destroy_class into the ...

CVE-2025-38477

In the Linux kernel, the following vulnerability has been resolved: net/sched: schqfq: Fix race condition on qfqaggregate A race condition can occur when 'agg' is modified in qfqchangeagg called during qfqenqueue while other threads access it concurrently. For example, qfqdumpclass may trigger a...

CVE-2025-38475

CVE-2025-38475 concerns the Linux kernel SMC socket type confusion where smc_sock hijacks AF_INET/AF_INET6 internals, causing inet_opt to be interpreted as a function pointer due to inet_sock not being the first member of smc_sock. The root cause is the misalignment between smc_sock and inet_sock...

CVE-2025-38474 usb: net: sierra: check for no status endpoint

In the Linux kernel, the following vulnerability has been resolved: usb: net: sierra: check for no status endpoint The driver checks for having three endpoints and having bulk in and out endpoints, but not that the third endpoint is interrupt input. Rectify the omission...

CVE-2025-38474

CVE-2025-38474 affects the Linux kernel USB Sierra network driver. The issue arises from not verifying that the driver’s third USB endpoint is an interrupt input, since the code only checked for three endpoints and bulk in/out. The fix “rectifies the omission” by validating the endpoint type. Ups...
