    NFSv4: remove callback IDR entry on client allocation failure

    In the Linux kernel, the following vulnerability has been resolved: NFSv4: remove callback IDR entry on client allocation failure nfs4_alloc_client() allocates an NFSv4.0 callback identifier before it finishes setting up the client. If any later initialization step fails, the error path frees the nfs_client directly with nfs_free_client(). That bypasses nfs_put_client(), which is where the callback IDR entry is removed during normal teardown. A failed allocation can therefore leave cb_ident_idr pointing at a freed nfs_client. A later NFSv4.0 callback lookup by cb_ident would find the stale pointer and take a reference to it. Make the call

    pnfs/blocklayout: Fix device leaks on parse failure

    In the Linux kernel, the following vulnerability has been resolved: pnfs/blocklayout: Fix device leaks on parse failure bl_parse_concat() and bl_parse_stripe() allocate a child device array and then parse each child in turn. If parsing a child fails, the failed child is not counted in nr_children and the parent may be left with a children array that bl_free_device() will not release when nr_children is zero. Release the failed child and the already parsed children before returning the error. Also make bl_free_device() release the child array whenever the children pointer is set, so that partially initialised concat or stripe devices are

    NFSv4/flexfiles: fix NULL dereference for NFSv4.0 data servers

    In the Linux kernel, the following vulnerability has been resolved: NFSv4/flexfiles: fix NULL dereference for NFSv4.0 data servers flexfiles accepts NFSv4.0 data servers, but two NFSv4 code paths assume the data server client has a session. Unlike NFSv4.1+, an NFSv4.0 client has no session (clp->cl_session is NULL; it uses clp->cl_slot_tbl), so I/O to a v4.0 flexfiles DS oopses: - nfs4_init_ds_session() dereferences clp->cl_session->session_state while seeding the DS lease. It also only seeds cl_lease_time when NFS4_SESSION_INITING is set; without a session that never happens, so cl_lease_time stays 0 and nfs4_renew_state() b

    NFSv4: Fix incorrect argument passed to nfs4_delete_lease() in nfs4_add_lease()

    In the Linux kernel, the following vulnerability has been resolved: NFSv4: Fix incorrect argument passed to nfs4_delete_lease() in nfs4_add_lease() When nfs4_add_lease() races with a delegation return, it calls nfs4_delete_lease() to clean up. Previously, it passed priv, which can legitimately be NULL. Passing a NULL priv eventually leads to a NULL pointer dereference in generic_setlease().

    bpf, xdp: move offload check into dev_xdp_install()

    In the Linux kernel, the following vulnerability has been resolved: bpf, xdp: move offload check into dev_xdp_install() bpf_xdp_link_update() calls dev_xdp_install() directly and skips dev_xdp_attach(), so the checks in dev_xdp_attach() do not run. A user can make an XDP link with a normal program and then swap in an offloaded or device-bound program with BPF_LINK_UPDATE, which puts it on the software path. dev_xdp_install() is the one place all three paths go through: "ip link set xdp" and BPF_LINK_CREATE reach it via dev_xdp_attach(), and BPF_LINK_UPDATE calls it directly. So move the program checks (offloaded, bound to another device, d

    net: kcm: Hold RCU read lock while running BPF parser

    In the Linux kernel, the following vulnerability has been resolved: net: kcm: Hold RCU read lock while running BPF parser kcm_parse_func_strparser() calls bpf_prog_run_pin_on_cpu() which prevents CPU migration, but does not establish an RCU read-side critical section. Consequently, BPF map operations can trigger WARN_ON_ONCE(!bpf_rcu_lock_held()) when called from the KCM strparser program. Hold the RCU read lock while running the program.

    ipvs: fix integer overflow in ftp helper port/address parsing

    In the Linux kernel, the following vulnerability has been resolved: ipvs: fix integer overflow in ftp helper port/address parsing ip_vs_ftp_get_addrport() accumulates decimal digits into a __u16 (hport) and into unsigned char (p[]) without checking for overflow. A crafted FTP PASV/EPSV response with an over-long port or address octet wraps the value, so the helper configures the data connection with a truncated port/address. The netfilter conntrack FTP helper had the same defect, fixed in commit 2b413fc689ba ("netfilter: nf_conntrack_ftp: avoid u16 overflows"). Apply the equivalent fix here: widen the port accumulator to u32 and reject val

    cuse: wait for pending RCU callbacks on module exit

    In the Linux kernel, the following vulnerability has been resolved: cuse: wait for pending RCU callbacks on module exit Since commit 053fc4f755ad ("fuse: fix UAF in rcu pathwalks"), fuse_conn_put() frees the fuse_conn through call_rcu() rather than synchronously. For cuse, fc->release is cuse_fc_release(), which lives in the cuse module. If the module is removed before the RCU grace period ends, the callback jumps into freed module memory: userspace / module unload | RCU softirq ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ close(/dev/cuse) | cuse_channel_release()

    In the Linux kernel, the following vulnerability has been resolved: rtc: pcf8563: fix clock provider leak on unbind pcf8563_clkout_register_clk() registers the CLKOUT clock provider with of_clk_add_provider(), but nothing ever unwinds it: there is no of_clk_del_provider() call and the driver has no remove callback. Each of_clk_add_provider() allocates a struct of_clk_provider, takes a reference on the OF node and adds an entry to the global of_clk_providers list, none of which is released when the device is unbound. Every bind/unbind (or module reload) therefore leaks a provider structure and an of_node reference. The clock itself is alrea

    In the Linux kernel, the following vulnerability has been resolved: ALSA: mtpav: shut down output timer before card teardown snd_mtpav_output_timer() rearms chip->timer while holding chip->spinlock and accesses the card-private mtpav state. snd_mtpav_free() currently takes the same lock and calls timer_delete() when the timer is active. This only removes a pending timer; it does not wait for a callback that is already running and does not prevent the callback from rearming the timer. A callback running on another CPU can therefore continue after snd_mtpav_free() releases the lock and access the card-private state while the card is being t

    net: bridge: Reject descending VLAN tunnel ranges

    In the Linux kernel, the following vulnerability has been resolved: net: bridge: Reject descending VLAN tunnel ranges A pair of descending VLAN and tunnel IDs can pass the tunnel range span check. The VLAN subtraction produces a negative int, which is converted to unsigned when compared with the u32 tunnel ID subtraction. It can therefore equal the wrapped tunnel ID delta. The range loop then performs no iterations. Since the batched notification handling added a post-loop error check, this leaves err uninitialized and makes the request's return value unpredictable. Reject descending VLAN ranges before comparing the spans. Valid ascending

    In the Linux kernel, the following vulnerability has been resolved: ip6mr: do not clone dst in ip6mr_cache_report() IPv6 input attaches a non-refcounted (NOREF) dst to skbs under RCU. When an ingress multicast packet misses MFC lookup, ip6mr_cache_unresolved() places the skb onto the unresolved queue, escaping the receive-side RCU grace period. If the underlying route is deleted and freed, and the MFC queue is later resolved with a wrong parent interface, ip6_mr_forward() invokes ip6mr_cache_report(..., MRT6MSG_WRONGMIF), which executes dst_clone(skb_dst(pkt)) on the freed dst entry, triggering a slab use-after-free.
