Vulnerabilities (CVE)

An issue was discovered in Bento4 v1.6.0-639. There is a memory leak in AP4_DescriptorFactory::CreateDescriptorFromStream in Core/Ap4DescriptorFactory.cpp, as demonstrated by mp42aac.

An out-of-bounds memory write flaw was found in the Linux kernel’s Kid-friendly Wired Controller driver. This flaw allows a local user to crash or potentially escalate their privileges on the system. It is in bigben_probe of drivers/hid/hid-bigbenff.c. The reason is incorrect assumption - bigben devices all have inputs. However, malicious devices can break this assumption, leaking to out-of-bound write.

A memory leak flaw was found in the UBI driver in drivers/mtd/ubi/attach.c in the Linux kernel through 6.7.4 for UBI_IOCATT, because kobj->name is not released.

In the Linux kernel, the following vulnerability has been resolved: af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC. syzbot reported a warning [0] in __unix_gc() with a repro, which creates a socketpair and sends one socket's fd to itself using the peer. socketpair(AF_UNIX, SOCK_STREAM, 0, [3, 4]) = 0 sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\360", iov_len=1}], msg_iovlen=1, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, ... In the Linux kernel, the following vulnerability has been resolved: af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC. syzbot reported a warning [0] in __unix_gc() with a repro, which creates a socketpair and sends one socket's fd to itself using the peer. socketpair(AF_UNIX, SOCK_STREAM, 0, [3, 4]) = 0 sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\360", iov_len=1}], msg_iovlen=1, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[3]}], msg_controllen=24, msg_flags=0}, MSG_OOB|MSG_PROBE|MSG_DONTWAIT|MSG_ZEROCOPY) = 1 This forms a self-cyclic reference that GC should finally untangle but does not due to lack of MSG_OOB handling, resulting in memory leak. Recently, commit 11498715f266 ("af_unix: Remove io_uring code for GC.") removed io_uring's dead code in GC and revealed the problem. The code was executed at the final stage of GC and unconditionally moved all GC candidates from gc_candidates to gc_inflight_list. That papered over the reported problem by always making the following WARN_ON_ONCE(!list_empty(&gc_candidates)) false. The problem has been there since commit 2aab4b969002 ("af_unix: fix struct pid leaks in OOB support") added full scm support for MSG_OOB while fixing another bug. To fix this problem, we must call kfree_skb() for unix_sk(sk)->oob_skb if the socket still exists in gc_candidates after purging collected skb. Then, we need to set NULL to oob_skb before calling kfree_skb() because it calls last fput() and triggers unix_release_sock(), where we call duplicate kfree_skb(u->oob_skb) if not NULL. Note that the leaked socket remained being linked to a global list, so kmemleak also could not detect it. We need to check /proc/net/protocol to notice the unfreed socket.

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The SMI handler for the FwBlockServiceSmm driver uses an untrusted pointer as the location to copy data to an attacker-specified buffer, leading to information disclosure.

Xenstore: Guests can create arbitrary number of nodes via transactions T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] In case a node has been created in a transaction and it is later deleted in the same transaction, the transaction will be terminated with an error. As this error is encountered only when handling the deleted node at transaction finalization, the transaction will have been performed partially and without updating the accounting information. This will enable a malicious guest to create arbitrary number of nodes.

A flaw was found in the src/list.c of tar 1.33 and earlier. This flaw allows an attacker who can submit a crafted input file to tar to cause uncontrolled consumption of memory. The highest threat from this vulnerability is to system availability.

A memory leak in the fsl_lpspi_probe() function in drivers/spi/spi-fsl-lpspi.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering pm_runtime_get_sync() failures, aka CID-057b8945f78f. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control these failures at probe time

drivers/bluetooth/virtio_bt.c in the Linux kernel before 5.16.3 has a memory leak (socket buffers have memory allocated but not freed).

open5gs v2.4.11 was discovered to contain a memory leak in the component src/smf/pfcp-path.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted PFCP packet.

open5gs v2.4.11 was discovered to contain a memory leak in the component src/upf/pfcp-path.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted PFCP packet.

CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. A memory leak vulnerability was identified in the `crypto_handle_incrementing_nontransmitted_counter` function of CryptoLib versions 1.3.3 and prior. This vulnerability can lead to resource exhaustion and degraded system performance over time, particularly in long-running processes or systems processing large volumes of data. The vulnerability is present in the `crypto_handle_incrementing_nontransmitted_counter` function within `crypto_tc.c`. The function allocates memory using `malloc` without ensuring the allocated memory is always freed. This issue can lead to resource exhaustion, reduced system performance, and potentially a Denial of Service (DoS) in environments where CryptoLib is used in long-running processes or with large volumes of data. Any system using CryptoLib, especially those handling high-throughput or continuous data streams, could be impacted. As of time of publication, no known patched versions are available.

In the Linux kernel, the following vulnerability has been resolved: udmabuf: fix memory leak on last export_udmabuf() error path In export_udmabuf(), if dma_buf_fd() fails because the FD table is full, a dma_buf owning the udmabuf has already been created; but the error handling in udmabuf_create() will tear down the udmabuf without doing anything about the containing dma_buf. This leaves a dma_buf in memory that contains a dangling pointer; though that doesn't seem to lead to anything bad except a memory leak. Fix it by moving the dma_buf_fd() call out of export_udmabuf() so that we can give it different error handling. Note that the shape of this code changed a lot in commit 5e72b2b41a21 ("udmabuf: convert udmabuf driver to use folios"); but the memory leak seems to have existed since the introduction of udmabuf.

This leads to a memory leak when the process exits as any pending entries in proc->delivered_freeze are not freed: unreferenced object 0xffff38e8cfa ... In the Linux kernel, the following vulnerability has been resolved: binder: fix memleak of proc->delivered_freeze If a freeze notification is cleared with BC_CLEAR_FREEZE_NOTIFICATION before calling binder_freeze_notification_done(), then it is detached from its reference (e.g. ref->freeze) but the work remains queued in proc->delivered_freeze. This leads to a memory leak when the process exits as any pending entries in proc->delivered_freeze are not freed: unreferenced object 0xffff38e8cfa36180 (size 64): comm "binder-util", pid 655, jiffies 4294936641 hex dump (first 32 bytes): b8 e9 9e c8 e8 38 ff ff b8 e9 9e c8 e8 38 ff ff .....8.......8.. 0b 00 00 00 00 00 00 00 3c 1f 4b 00 00 00 00 00 ........<.K..... backtrace (crc 95983b32): [<000000000d0582cf>] kmemleak_alloc+0x34/0x40 [<000000009c99a513>] __kmalloc_cache_noprof+0x208/0x280 [<00000000313b1704>] binder_thread_write+0xdec/0x439c [<000000000cbd33bb>] binder_ioctl+0x1b68/0x22cc [<000000002bbedeeb>] __arm64_sys_ioctl+0x124/0x190 [<00000000b439adee>] invoke_syscall+0x6c/0x254 [<00000000173558fc>] el0_svc_common.constprop.0+0xac/0x230 [<0000000084f72311>] do_el0_svc+0x40/0x58 [<000000008b872457>] el0_svc+0x38/0x78 [<00000000ee778653>] el0t_64_sync_handler+0x120/0x12c [<00000000a8ec61bf>] el0t_64_sync+0x190/0x194 This patch fixes the leak by ensuring that any pending entries in proc->delivered_freeze are freed during binder_deferred_release().
