SUSE CVE-2026-43202
In the Linux kernel, the following vulnerability has been resolved: fbdev: vt8500lcdfb: fix missing dmafreecoherent fbi-fb.screenbuffer is allocated with dmaalloccoherent but is not freed if the error path is reached...
CVE-2026-43149
A flaw was found in the Linux kernel's fslucchdlc module. The uhdlcmemclean function incorrectly deallocates memory by calling dmafreecoherent twice for buffers that were allocated as a single contiguous block. This improper memory handling may lead to a denial of service DoS or other unpredictab...

In the Linux kernel, the following vulnerability has been resolved: fbdev: vt8500lcdfb: fix missing dmafreecoherent fbi-fb.screenbuffer is allocated with dmaalloccoherent but is not freed if the error path is reached...
CVE-2026-43283
The CVE-2026-43283 issue is in the Linux kernel's ec_bhf Ethernet driver where error-path handling used priv->rx_buf.alloc_len as the DMA handle in dma_free_coherent(), risking improper unmapping and potential memory corruption or DoS. The fix changes the DMA handle to priv->rx_buf.alloc_ph...
CVE-2026-43283
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ecbhf: Fix dmafreecoherent dma handle dmafreecoherent in error path takes priv-rxbuf.alloclen as the dma handle. This would lead to improper unmapping of the buffer. Change the dma handle to priv-rxbuf.allocphys...
PT-2026-37623
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ec bhf ethernet driver where the dma free coherent function in the error path incorrectly uses priv-rx buf.alloc len as the DMA handle. This results in the imprope...
PT-2026-37542
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the fbdev component, specifically within the vt8500lcdfb driver, the fbi-fb.screen buffer is allocated using the dma alloc coherent function but is not properly released via dma free...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the dmaalloccoherent function in the vt8500lcdfb driver. The memory allocated by this function is...
SUSE CVE-2026-23135
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dmafreecoherent pointer dmaalloccoherent allocates a DMA mapped buffer and stores the addresses in XXXunaligned fields. Those should be reused when freeing the buffer rather than the aligned addresses...
CVE-2026-23135 wifi: ath12k: fix dma_free_coherent() pointer
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dmafreecoherent pointer dmaalloccoherent allocates a DMA mapped buffer and stores the addresses in XXXunaligned fields. Those should be reused when freeing the buffer rather than the aligned addresses...
PT-2026-8128
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel’s wifi subsystem, specifically within the ath10k driver, related to the handling of DMA Direct Memory Access mapped buffers. The issue involves incorrec...
CVE-2023-54231 net: libwx: fix memory leak in wx_setup_rx_resources
In the Linux kernel, the following vulnerability has been resolved: net: libwx: fix memory leak in wxsetuprxresources When wxallocpagepool failed in wxsetuprxresources, it doesn't release DMA buffer. Add dmafreecoherent in the error path to release the DMA buffer...
