CVE-2025-38195

CVE-2025-38195 concerns the Linux kernel LoongArch code, where a NULL-PMD handling path in huge_pte_offset() could trigger a kernel-panic when processing huge pages, as shown by the error trace and mitigation notes. The issue affects the kernel’s page fault / madvise pathways, with a local attack...

CVE-2025-38194

CVE-2025-38194 affects the Linux kernel’s JFFS2 file system. The issue arises when jffs2_sum_write_sumnode does not validate the return value of jffs2_prealloc_raw_node_refs, allowing an preallocation error to propagate into jffs2_link_node_ref and potentially cause a kernel BUG at fs/jffs2/nodel...

CVE-2025-38193 net_sched: sch_sfq: reject invalid perturb period

In the Linux kernel, the following vulnerability has been resolved: netsched: schsfq: reject invalid perturb period Gerrard Tai reported that SFQ perturbperiod has no range check yet, and this can be used to trigger a race condition fixed in a separate patch. We want to make sure ctl-perturbperio...

CVE-2025-38193

CVE-2025-38193 affects the Linux kernel net_sched SFQ (sch_sfq). The issue is a missing range check on perturb_period, which can enable a race condition; patches fix perturb_period overflow/invalid values. Public demonstrations show negative, oversized, and a valid perturb value (2000000), with t...

CVE-2025-38192

CVE-2025-38192 is a Linux kernel vulnerability where an ingress NAT46 BPF program that flips IPv4/IPv6 can mutate skb->protocol to v6 while the dst remains IPv4, leading to a NULL pointer dereference in ip6_rcv_core. The fix is to clear the destination (dst) in all BPF helpers that change skb-...

CVE-2025-38192 net: clear the dst when changing skb protocol

In the Linux kernel, the following vulnerability has been resolved: net: clear the dst when changing skb protocol A not-so-careful NAT46 BPF program can crash the kernel if it indiscriminately flips ingress packets from v4 to v6: BUG: kernel NULL pointer dereference, address: 0000000000000000...

CVE-2025-38190

In the Linux kernel, the following vulnerability has been resolved: atm: Revert atmaccounttx if copyfromiterfull fails. In vccsendmsg, we account skb-truesize to sk-skwmemalloc by atmaccounttx. It is expected to be reverted by atmpopraw later called by vcc-dev-ops-sendvcc, skb. However, vccsendms...

CVE-2025-38191

Summary: The Linux kernel ksmbd component has a null-pointer dereference in destroy_previous_session during Kerberos session setup when PreviousSessionId is used. The root cause is that sess->user is not yet set, allowing a NULL user to be passed to destroy_previous_session. Fix: The patch def...

CVE-2025-38191 ksmbd: fix null pointer dereference in destroy_previous_session

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference in destroyprevioussession If client set -PreviousSessionId on kerberos session setup stage, NULL pointer dereference error will happen. Since sess-user is not set yet, It can pass the user...

CVE-2025-38190

CVE-2025-38190 affects the Linux kernel ATM path. The issue arises when in the vcc_sendmsg() path, skb->truesize is accounted to sk_wmem_alloc via atm_account_tx(), but the corresponding revert is not performed on copy_from_iter_full() failure, potentially leaking a socket. The fixed approach ...
