CVE-2026-71236

Grocy is affected by CVE-2026-71236 due to a flaw in its API request-body parser: after HTMLPurifier cleans values, the code re-decodes certain HTML entities (<, >, &) to , and &, effectively reconstructing live HTML/script tags. This double-decoding reintroduces stored XSS in API-writa...

CVE-2026-64581

In the Linux kernel, the following vulnerability has been resolved: xfrm: fix skdstcache double-free in xfrmuserpolicy xfrmuserpolicy clears the socket dst cache with skdstreset, i.e. the non-atomic skdstsetsk, NULL: it reads skdstcache with rcudereferenceprotected, stores NULL and dstreleases th...

CVE-2026-64581

CVE-2026-64581: Linux kernel XFRM double-free in xfrm_user_policy() due to non-atomic sk_dst_cache updates. A per-socket policy change can race with UDP transmit path, causing both sides to release the same dst and freeing the xfrm_dst bundle twice. The fix uses an atomic sk_dst_reset() with a si...

CVE-2026-64580

The CVE-2026-64580 entry describes a Linux kernel issue in xfrm6 where on error path the code releases a device reference with netdev_put() but leaves xdst->u.dst.dev set, causing a double netdev_put on dst->dev and underflow of the net_device refcount. The fix, as detailed in the disclosur...

CVE-2026-64575

The CVE-2026-64575 issue affects the Linux kernel’s BPF TCP batch iterator. The root cause is a double release of socket references during batch realloc; on realloc failure, cur_sk/end_sk remain and later code dereferences a cookie as a struct sock, causing a null-ptr-deref in __sock_gen_cookie a...

CVE-2026-64570

In CVE-2026-64570, Linux kernel wifi/mac80211 fixes a double-free in FILS discovery: ieee80211_set_fils_discovery() frees the old template with kfree_rcu() before allocating the replacement. If kzalloc() fails (ENOMEM), link->u.ap.fils_discovery still points to the old object, and a later AP t...

CVE-2026-64568

CVE-2026-64568 affects the Linux kernel’s mac80211/wifi stack. The vulnerability arises in ieee80211_set_unsol_bcast_probe_resp(): it frees the old unsol_bcast_probe_resp template with kfree_rcu() before a replacement has been allocated. If kzalloc() fails, link->u.ap.unsol_bcast_probe_resp st...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...
