In the Linux kernel, the following vulnerability has been resolved: net: dsa: felix: Fix memory leak in felix_setup_mmio_filtering Avoid a memory leak if there is not a CPU port defined. Addresses-Coverity-ID: 1492897 ("Resource leak") Addresses-Coverity-ID: 1492899 ("Resource leak")
CVE-2021-47516 1 Linux 1 Linux Kernel 2024-06-10 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: nfp: Fix memory leak in nfp_cpp_area_cache_add() In line 800 (#1), nfp_cpp_area_alloc() allocates and initializes a CPP area structure. But in line 807 (#2), when the cache is allocated failed, this CPP area structure is not freed, which will result in memory leak. We can fix it by freeing the CPP area when the cache is allocated failed (#2). 792 int nfp_cpp_area_cache_add(struct nfp_cpp *cpp, size_t size) 793 { 794 struct nfp_cpp_area_cache *cache; 795 struct nfp_cpp_area *area; 800 area = nfp_cpp_area_alloc(cpp, NFP_CPP_ID(7, NFP_CPP_ACTION_RW, 0), 801 0, size); // #1: allocates and initializes 802 if (!area) 803 return -ENOMEM; 805 cache = kzalloc(sizeof(*cache), GFP_KERNEL); 806 if (!cache) 807 return -ENOMEM; // #2: missing free 817 return 0; 818 }
CVE-2021-47519 1 Linux 1 Linux Kernel 2024-06-10 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: can: m_can: m_can_read_fifo: fix memory leak in error branch In m_can_read_fifo(), if the second call to m_can_fifo_read() fails, the function jump to the out_fail label and returns without calling m_can_receive_skb(). This means that the skb previously allocated by alloc_can_skb() is not freed. In other terms, this is a memory leak. This patch adds a goto label to destroy the skb if an error occurs. Issue was found with GCC -fanalyzer, please follow the link below for details.
CVE-2021-47529 1 Linux 1 Linux Kernel 2024-06-10 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: iwlwifi: Fix memory leaks in error handling path Should an error occur (invalid TLV len or memory allocation failure), the memory already allocated in 'reduce_power_data' should be freed before returning, otherwise it is leaking.
CVE-2021-47537 1 Linux 1 Linux Kernel 2024-06-10 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Fix a memleak bug in rvu_mbox_init() In rvu_mbox_init(), mbox_regions is not freed or passed out under the switch-default region, which could lead to a memory leak. Fix this bug by changing 'return err' to 'goto free_regions'. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_OCTEONTX2_AF=y show no new warnings, and our static analyzer no longer warns about this code.
CVE-2021-47546 1 Linux 1 Linux Kernel 2024-06-10 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: ipv6: fix memory leak in fib6_rule_suppress The kernel leaks memory when a `fib` rule is present in IPv6 nftables firewall rules and a suppress_prefix rule is present in the IPv6 routing rules (used by certain tools such as wg-quick). In such scenarios, every incoming packet will leak an allocation in `ip6_dst_cache` slab cache. After some hours of `bpftrace`-ing and source code reading, I tracked down the issue to ca7a03c41753 ("ipv6: do not free rt if FIB_LOOKUP_NOREF is set on suppress rule"). The problem with that change is that the generic `args->flags` always have `FIB_LOOKUP_NOREF` set[1][2] but the IPv6-specific flag `RT6_LOOKUP_F_DST_NOREF` might not be, leading to `fib6_rule_suppress` not decreasing the refcount when needed. How to reproduce: - Add the following nftables rule to a prerouting chain: meta nfproto ipv6 fib saddr . mark . iif oif missing drop This can be done with: sudo nft create table inet test sudo nft create chain inet test test_chain '{ type filter hook prerouting priority filter + 10; policy accept; }' sudo nft add rule inet test test_chain meta nfproto ipv6 fib saddr . mark . iif oif missing drop - Run: sudo ip -6 rule add table main suppress_prefixlength 0 - Watch `sudo slabtop -o | grep ip6_dst_cache` to see memory usage increase with every incoming ipv6 packet. This patch exposes the protocol-specific flags to the protocol specific `suppress` function, and check the protocol-specific `flags` argument for RT6_LOOKUP_F_DST_NOREF instead of the generic FIB_LOOKUP_NOREF when decreasing the refcount, like this.

CVE-2023-31973 1 Tortall 1 Yasm 2024-06-04 N/A 5.5 MEDIUM
yasm v1.3.0 was discovered to contain a use after free via the function expand_mmac_params at /nasm/nasm-pp.c. Note: Multiple third parties dispute this as a bug and not a vulnerability according to the YASM security policy.
CVE-2020-8991 1 Redhat 1 Lvm2 2024-06-04 2.1 LOW 2.3 LOW
vg_lookup in daemons/lvmetad/lvmetad-core.c in LVM2 2.02 mismanages memory, leading to an lvmetad memory leak, as demonstrated by running pvs. NOTE: RedHat disputes CVE-2020-8991 as not being a vulnerability since there’s no apparent route to either privilege escalation or to denial of service through the bug
CVE-2020-12656 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2024-06-04 2.1 LOW 5.5 MEDIUM
gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c in the rpcsec_gss_krb5 implementation in the Linux kernel through 5.6.10 lacks certain domain_release calls, leading to a memory leak. Note: This was disputed with the assertion that the issue does not grant any access not already available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of memory they like and load that replicating the effect of this bug
CVE-2019-19065 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2024-06-04 4.7 MEDIUM 4.7 MEDIUM
A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures, aka CID-34b3be18a04e. NOTE: This has been disputed as not a vulnerability because "rhashtable_init() can only fail if it is passed invalid values in the second parameter's struct, but when invoked from sdma_init() that is a pointer to a static const struct, so an attacker could only trigger failure if they could corrupt kernel memory (in which case a small memory leak is not a significant problem).
CVE-2024-24267 1 Gpac 1 Gpac 2024-05-28 N/A 7.5 HIGH
gpac v2.2.1 was discovered to contain a memory leak via the gfio_blob variable in the gf_fileio_from_blob function.
CVE-2024-5294 2024-05-24 N/A 4.3 MEDIUM
D-Link DIR-3040 prog.cgi websSecurityHandler Memory Leak Denial-of-Service Vulnerability. This vulnerability allows network-adjacent attackers to create a denial-of-service condition on affected installations of D-Link DIR-3040 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the prog.cgi program, which handles HNAP requests made to the lighttpd webserver listening on ports 80 and 443. The issue results from the lack of proper memory management when processing HTTP cookie values. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. .

CVE-2024-27012 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2024-05-23 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: restore set elements when delete set fails From abort path, nft_mapelem_activate() needs to restore refcounters to the original state. Currently, it uses the set->ops->walk() to iterate over these set elements. The existing set iterator skips inactive elements in the next generation, this does not work from the abort path to restore the original state since it has to skip active elements instead (not inactive ones). This patch moves the check for inactive elements to the set iterator callback, then it reverses the logic for the .activate case which needs to skip active elements. Toggle next generation bit for elements when delete set command is invoked and call nft_clear() from .activate (abort) path to restore the next generation bit.
